Evans, C. J.

*677 *676 The contract sued upon was made, if at all, in January, 1923. The defendant was a going corporation, which had been in business in Cedar Rapids for several years. The *677 contract alleged to have been made- with plaintiff was so made between him and one. Bennett, on behalf of the corporation. Bennett was used as a witness by the plaintiff. -. Both Bennett and plaintiff- testified to the terms of the contract. These were, in substance, that the plaintiff should receive as his compensation for the year 1923 a sum equal to 3 per cent of the gross business to be transacted in that year. Such gross business amounted to approximately $250,000. The amount of compensation claimed amounted approximately to $7,500. ' There were no witnesses to the contract other than plaintiff and- Bennett. No record had ever been made of such contract, nor had it ever been reported to the defendant's board of directors. No direct evidence was available to the defendant to contradict the testimony of the plaintiff and Bennett as to the making of such contract. The defendant relied wholly upon evidence of circumstances which tended to show that the contract was unreasonable and improbable, and tended otherwise to impair or impeach the credibility of the testimony of the plaintiff and his witness. Some of the facts-and circumstances thus relied on are undisputed.in the record; others were elicited upon crossrexainination of .plain-: tiff; and others were sought to be- thus elicited, but were rejected by the rulings of the court. Still other- circumstances were sought to be shown by 'independent evidence, but were rejected by the rulings of the court. Though a large number of errors are assigned, the major' question! presented'upon-this record is whether the court properly directed a verdict, for-the plaintiff for the full amount of his claim, on the ground that the positive evidence of the plaintiff and his witness was uneontradieted by any direct evidence. In view of the necessity of awarding a new trial; we shall avoid, as far as possible, an undue discussion of the details of the .evidence, and devote our consideration to what we deem to be the fundamental error in the case. This was the holding by the court that the facts and circumstances put and offered in evidence by the defendant neither tended to contradict the positive evidence of the plaintiff nor to impair its credibility. -"

' "We have consis-téntly held that a mere failure to produce direct contradiction to the testimony of: a witness does not -necessarily entitle such testimony to be deemed true. It must still *678 stand the test of credibility, in the light of all the circumstances surrounding the transaction. - This is-particularly true in those cases where, from its very nature, no evidence is available to the -adverse party to contradict such testimony. We have also held that it is a rare case' where-a party having the-burden of proof can- be entitled to a directed- verdict. Circumstances may be produced and relied on to show -improbability and unreasonable^ ness and inconsistency, and the nature ■ of such -circumstances is as varied, and the scope-thereof as wide,'as the field of human affairs. Holmes v. Connable, 111 Iowa 298; Arnd v. Ayles worth, 145 Iowa 185; Bremer v. Haag, 151 Iowa 449; In re Estate of Chismore, 166 Iowa 217; Young v. McClannahan, 187 Iowa 1184. The general nature-of the facts and'circumstances relied upon by the defendant will appear-in the following recital : Prior to December 2, 1922, one Strasburger was the majority stockholder and general manager-, of the business of the corporation. On the date named, he died. Next in interest in the corporation was Behnett, whose'wife owned 31- per cent of the stock. At the time- of the-death of Strasburger; the plaintiff had been in the employ of defendant-corporation as a bookkeeper for the period of one year. His employment began upon a salary of $35 per week, which sum was raised to'$50 per week sometime prior to-January 1,- 1923. Upon-the death of Strasburger, Bennett became'the general manager. 'One of the contentions-pressed by the defendant-was that, upon the death-of Strasburger, Bennett and the plaintiff entered into collusion to manipulate the business of the'company to'their own benefit; and that they--worked together to that end. On-or before January 1, 1923, the plaintiff became'a stockholder, director, and vice president of the corporation. The 'extent of his interest as stockholder is not disclosed in the record; but the • inferences therefrom are that such interest was nominal. At a directors’ meeting on January 1, 1923, the plaintiff offered the following resolution:

“And thereupon, the said directors and officers still being present, A. E.-Schulte [plaintiff] presented the following resolution and moved its adoption: ‘ .....

“Resolved, thA Henry Bennett be continued as manager for the ensuing year, of the Ideal-Food Products Company (Del.) and that he, as such manager, is hereby delegated general powers *679 to manage the business and affairs of the company, to hire employes and fix the pay. and salaries thereof, including his salary, and the right to. discharge such employes, to.purchase goods for manufacturing, purposes, to make or authorize sales thereof, and to carry out the.method and plans of conducting the company’s business adopted in the past, and is authorized to draw checks on moneys deposited, in the hank or elsewhere, and to do all things necessary with .a-view of carrying out the object of the. company, and as in his judgment may seem best.”

This resolution, had been prepared by Bennett. It was carried, and became a part of the record of the meeting, and was put in .evidence by the plaintiff in proof of the authority of Bennett to make the contract alleged with the plaintiff. N.o memorandum . or record of this contract was ever made, .nor was it ever reported to the directors. The evidence- tended to show harmonious co-operation between Bennett and the - plaintiff. Friction arose, however, as between them and the other interests. A meeting of stockholders was called by due notice upon May 26, 1923.. This call was hostile to Bennett and. to the plaintiff. At such. meeting, Mrs. Strasburger (widow of Strasburger) was elected as manager, in lieu of Bennett. Immediately preceding the directors’ meeting, the plaintiff drew, and Bennett signed, three, cheeks, purporting to be drawn by the company, as follows: On .May 25th, one check for $2,500, payable to plaintiff, and one for $8,000 payable to Bennett.; ,and again on May 26th, one’ check for $10,500, payable to Bennett. These checks were immediately - cashed. The .defendant claims that the issue of these checks was wrongful and fraudulent. In .subsequent litigation, -Bennett, was required to return $13,500 of the amount thus drawn by him. In subsequent litigation also, the plaintiff testified concerning the $2,500 check issued to himself, and such testimony figures in the present record.

Owing to contesting ■ litigation, Mrs. Strasburger did not taire possession of the office as manager, until .August 8th. In the meantime,, the plaintiff and Bennett continued in charge of the business. On August. 8th, the right to conduct the business as manager was judicially awarded to Mrs. Strasburger; wherer upon she appeared at the office of the corporation, with her attorney, while plaintiff was-in charge thereof, and requested possession of the books, of the corporation, and particularly the rec *680 ord of checks drawn. The plaintiff refused to comply with such request. He immediately placed all the records in the safe and locked the same. The combination of the safe was unknown to Mrs. Strasburger and to her helpers, and she finally gained access to the Contents of the safe only after a week’s effort, and with the help of experts, who drilled the same. Immediately after thus locking the safe, the plaintiff secretly drew another cheek, payable to himself; for $1,500, and later obtained the signature of Bennett thereto. Before it was presented at the bank, payment had been stopped thereon. Because of his conduct here recited, Mrs. Strasburger purported then and there to discharge him. The defendant offered other testimony tending to sustain the rightfulness of the plaintiff’s discharge, but the court refused this evidence. In the final ruling, the court held, as a matter of law, that the discharge by Mrs. Strasburger was wrongful, and that the plaintiff was entitled- to compensation, based upon the business of the corporation, for the full calendar year of 1923.

It appears also that, from the first of January, 1923, the plaintiff had drawn regularly $50 a week, to a sum total of $1,550, up to August 8th. One week after his discharge, he was a witness in a case pending between the defendant-company and Bennett, and was interrogated therein concerning his own attitude as to his right of compensation from the defendant-company. On that occasion, he apparently took the ground that $50 per week was to pay him only for his services as bookkeeper, and that he was entitled to extra compensation for special services. A part of the record of his evidence at that time is as follows:

“Q. So altogether you' claim your extra services amounted to $4,000? A. Yes, that was the agreed price. Q. All the extra work that you drew the $4,000 check for, was done while you were drawing* - a regular weekly salary from this company as bookkeeper at.$35 per week to start with, and $50 per week up until the time you quit down there? A. Yes, sir. Q. This $4,000 had no specific application at all; it was just payment on general claims, without being specified what the claims were,— is that correct? A. Just a recognition of special services, — call it claim or whatever you are a mind to. Q. You put in a full day as bookkeeper and $4,000 worth of work besides, did you? A. Yes. Q. But you drew put $2,500 of the company’s money on that day ? A. I did. Q. What was that for ? A. For spe *681 eial services. Q. What was the $1,500 cheek for you for? A. The same proposition. Q. Are there any other checks coming to you on that same proposition?. A.. Not that I know of.”

Upon the trial of the case at bar, the plaintiff was interrogated concerning his former evidence. The record above quoted was laid before him, and he was thereupon interrogated as follows:

“Were those questions asked you, and did you make those answers at that time and place? A. I don’t recall now, — possibly I did. Q. You say you possibly did? A. I wouldn’t care to testify,- without the record on that particular case, although I am not positive. Q. I will hand you the record, if it will refresh your recollection. [Counsel hands witness transcript of former testimony.] Read that record, and then state to the court if you are not quite positive that you did make those answers to those questions at that time. A. I wouldn’t know any more about it after reading the record than before.

“Mr. Johnson: What is your best recollection? Is it your judgment that you answered them or that you didn’t? Answer this question. A. I don’t recall whether I did or didn’t.”

His testimony in the case at bar is that his contract with Bennett gave him 3 per cent of the gross sales, and that the $50 per week was to be applied as part payment thereon. Nothing was said in his former evidence concerning 3 per cent, and nothing is claimed in his present testimony concerning pay for special services.

*682 *681 The foregoing is a sufficient statement to indicate the character of defendant’s challenge to the credibility of plaintiff’s testimony. It may be added that defendant’s counsel pressed diligently upon the attention of the. trial court the contention that, because the plaintiff and Bennett were directors of the corporation, they sustained a fiduciary relation thereto, and that they were not at liberty to make contracts in its behalf beneficial to themselves without subjecting such contract to the test of reasonableness and good faith. As against the foregoing, the appellee contends that the defendant’s pleading did not warrant the consideration of the matters here set forth, and especially that the plea of fraud was bad, for want of specification. The third division of defendant’s answer, purporting to plead *682 fraud and collusion, was indeed inadeq~iate for ~ny affirmative piirpo~e. The an~we~ did plead adequately the diseharp of th~ p1aini~i~ on August 8th. The ma~t~ers above set forth ~.vere, in the main, legally available to the defendant in support of its general denial, and without any pleading asking affirmative relief. It was all matter, which could have been inquired into on cross-examination of the plaintiff. Much of the rejected evidence was so rejected on cross-examination. As to adverse rulings rejecting evidence, it is-argued by appellee that érror, if any, is not available to the appellant, for want of a showing or statement as to .what the evidence would be, if. answer had been permitted. The rule thus invoked has little, if any, application to cross-examination, and especially to the cross-examination of a hostile witness. The right of cross-examination of the adversary's witness is. quite distinct in character from the right .of a party to examine his' own witness for the purpose .of adducing facts. The rig*ht to cross-examine is quite absolute. It inheres in the right of the adversary to use the' testimony of the witness, at all. One of its purposes is to test the credibility of the witness. The refusal of such right cannot be justified by saying that the answer of the witness would not have been favorable to the cross-examiner. Unfavorable answers are often as dangerous to the witness as favorable ones. An answer unfavorable to the cross-examiner may .be more incredible than a favorable one would.have been. If incredible, the credibility of the witness is thereby impaired. The consistency of the witness also may be thus put'to, the test. In Glassman v. Chicago, R. I. & P. R. Co., 166 Iowa 254, we, said that the .refusal of proper cross-examination was “a denial of an absolute right, and has been generally held'to be sufficient ground for reversal.” . .

But the main argument is.directed.to the contention that these matters above set forth did not in any manner.contradict or negative the alleged contract testified to by Bennett and by the plaintiff, and that, whatever might be said as to these -collateral matters, such principal testimony still stood uncontradicted. This argument discloses in a nutshell the .erroneous conception of the law which underlies the entire record. It carries the assumption that a burden rested upon the defendant to dis *683 prove something. This was: exemplified by-the court at the time of sustaining the final motion, as is indicated, by-.the-following excerpts from the stated reasons which.influenced the- court to the -decision reached: ...

“Now, respecting plaintiff’s motion for. a directed verdict. This presents the real question in this case: that is, whether or not there-is sufficient, evidence in. the, record to; support a verdict for the defendant in case.the- jury should return a -verdict for the defendant. . That involves: 1st, the question as to whether or not there is sufficient evidence from which the jury .could find that the alleged.oral contract sued upon was. not entered into between the defendant corporation and the plaintiff. * * *.

- • “Now, Mr. .Bennett testified that he did make the contract, and Mr. Schulte testifies that the contract was in fact made. This testimony is clear. Now, what is there in the record to dispute the testimony of Mr. Bennett and the. testimony of; Mr. Schulte on that proposition? * * '* And it is -claimed-that these alleged.statements.tend to show that this contract was not in fact made. There is no statement in that record by .Mr. Schulte to the effect that the contract was not made. His- alleged admissions, to say the most, are mere inferences that the contract sued upon now was not in fact made.

“The question there is whether or not there is any statement made by Mr. Schulte on the former trial which is inconsistent and which, disputes his testimony, given on the trial of. this case, and whether it disputes to such- an extent and to such, a' degree as that it is sufficient evidence upon which to support a verdict in fa/vor of .the defendant upon that point if the verdict should be in favor, of .the defendant, in ease it were submitted to the jury upon that branch. * *

“I think-in this ease, if this jury should bring in a verdict for defendant, finding that this contract was not in fact entered into, it-would be lacking, in that sufficient degree of proof that the law requires to support it, and it would be the duty of the court to set it aside. * * * .- ■ , . -

“The Court: I think, Mr. Dennis, .that:it .is inferences that might be drawn from this admission. They are mere inferences, and those inferences to be drawn from those alleged admissions are not of sufficient weight to .outweigh the positive statement of *684 Mr. Schulte to the effect that they did engage in and did enter into this contract. '

• ■ “Now, it is a well settled rule of law, too, that a mere inference, or mere inferences, are not of sufficient weight to carry an issue to the jury, in the face of and against positive testimony to the contrary. * * *

“Now, there is no dispute as- to what was said at that time, excepting as you claim that by inference that Mr. Schulte admitted- something to the -contrary when he testified in the trial of the'other case. # * *

■ ■ • “I am satisfied it would be the duty of the court to set aside any verdict this jury might return in favor-of the defendant upon the proposition that this contract was not entered into. It would be lacking in any sufficient support, — it would be lacking in that degree of strength and force that the law requires, upon which" the jury might base a finding.” , '

It will’be seen from the foregoing that the court deemed it its duty to hold the defendant to an affirmative burden of proof. There was no burden upon the-defendant. The burden was at all times upon the plaintiff, not only to produce affirmative testimony in support of his claim, but such testimony as should command the credence of the jury, in the light of all the circumstances surrounding the transaction.- Positive evidence may he overcome by' unfavorable inferences arising out of collateral circumstances. This is often the only test available, and often, too, -a most effective one. There was no burden upon the defendant to prove that the “contract was not made.” Nor was it requisite that the jury should find that the contract was not made, in order to render a verdict for the defendant. A verdict for the defendant would have meant that the credibility of plaintiff's testimony had failed, in the light of all the circumstances disclosed.

■ The circumstances here indicated were quite abundant as a challenge ’to the credibility-of the evidence on behalf of plaintiff, and should not have been ignored, as such. The weight of plaintiff's evidence became clearly a question for thé jury, and the order directing a verdict for the plaintiff for the full amount of his claim was necessarily erroneous.

In our foregoing statement of the facts and circumstances relied upon by the defendant, we are not to be understood as *685 expressing or intimating onr own present views as to the weight of defendant’s evidence or. as to the truth or falsity thereof. Nor are we to. be understood as expressing or intimating our view as to the truth or. falsity of the plaintiff’s testimony. What we hold is that the question of truth or falsity of all the evidence was clearly for the jury.

The judgment below is, accordingly, reversed. — Reversed.
