Defendant was convicted by court trial of violation of sections 288 and 288a of the Penal Code, sexual offenses upon a female child 8 years of age. Defendant appeals from the order of the trial court denying a new trial. (Pen. Code, § 1237, subd. 2.)
Contentions on appeal are generally that (1) the child prosecutrix, by reason of inability to receive just impressions and to relate them truly, failed to qualify as a competent witness; that her testimony was uncorroborated with respect to the convicting acts; (2) the evidence was insufficient, assuming the child’s competency as a witness, to support the judgment because (a) there was no expert testimony corroborating the child’s testimony, (b) prosecuting witnesses contradicted the testimony of the child witness, resulting in a fatal lack of corroboration, (c) the child witness was inconsistent and contradictory in her testimony, (d) the child’s testimony was conditioned through the mother’s discussion, in the child’s presence, of purported facts and circumstances of the alleged offenses; (3) the attempted impeachment of the mother as a coprosecutrix was prevented by the trial court and was error; (4) proffered new evidence on the motion for a new trial would probably have caused a different *561 result; and (5) the combination of the foregoing conditions, in view of the heinous nature of the offenses charged and the difficulty to defend against same, should, justly, require a new trial.
I
Defendant strongly attacks the competency of the child witness. It is unnecessary to repeat the testimony tending to establish the credibility and competency of the child. The provisions of section 1880, subdivision 2, of the Code of Civil Procedure, to the effect that “Children under ten years of age, who appear incapable of receiving just impressions of the facts respecting which they are examined, or of relating them truly” cannot be witnesses, were found inapplicable by the trial court. Such determination should not be disturbed on appeal where there is substantial evidence to support it.

The evidence was sufficient to support the judgment. There were no eyewitnesses to the exact sexual offenses, and no evidence of physical harm, nor other corroboration. However, corroboration is not prerequisite to a conviction of a crime of this nature.

III
Upon the motion for new trial, newly discovered evidence was asserted by defendant which consisted only of good character witnesses. There is nothing in the record nor in the argument of counsel to indicate that such form of evidence was unavailable at the time of trial. Counsel on appeal did not represent defendant at the trial but the trial judge was confronted with the issue of the probability of a different result in the event such additional evidence was before the court upon a new trial.

Defendant attempted to cross-examine the child’s mother by inquiring if she had complained of advances made to her by various men. The court rejected the proffer. We think it was in error. It is well established that such eases as these are fraught with great danger, since the charge rests on the credibility of a child witness against the defendant’s denial. Especially where, as here, there is a total lack of corroboration, a belated complaint by the child to her mother, and a marked inconsistency in her testimony, the courts must heed the admonition of our Supreme Court in

v.
Adams
(1939)
In addition to the problems inherent in the testimony of the child herself, such cases usually involve, also, problems inherent in the testimony of a mother or other relative. Normally, it is from such a person that information of the alleged offense comes to the prosecution. But we know that, for some women, the normal concern for the welfare of their child may take an aggravated form. If the mother is abnormally oriented toward sexual conduct, and has an abnormal fear of and reaction to sexual relations, she may, quite unconsciously, build up, in her own mind, a quite innocent act or caress into a grievous wrong. Young children are especially suggestible. The inquiries put by such a mother to her daughter may, themselves, implant into the child’s mind ideas and details which existed only in the fears and fantasies of the adult. Once implanted, they become quite real in the mind of the child witness and are impervious to cross-examination.
In addition, experience has shown that a mother may be motivated by actual malice, fear, retribution, retaliation, *564 jealousy, or other motives of her own toward defendant and either by design, or unintentionally, may have implanted in the child’s mind, nonexistent details which convert an innocent act into a heinous one.
For the same reasons that require a broad freedom of exploration of the child’s propensities to fabricate or to imagine sexual crimes, we think a defendant should be allowed to explore, within reasonable range, the possibility of similar propensities or motivation on the part of the adult from and through whom the charge to authority emanates in alleged crimes of this nature.
In the instant ease, no witness corroborated the child’s story; no physical evidence of molestation existed. Under these circumstances, it seems to us error to deny to the defendant a reasonable opportunity to explore the not impossible existence of such a morbid fear of sexual acts in the mind of the mother as to make the charge a creature of that morbidity.
Reasonable latitude in cross-examination is likewise indicated in a ease, such as here, where four witnesses, none of whom was acquainted with defendant, testified that the reputation of the mother for truthfulness was not good. In such instances, the possibilities of fabrication are enormous and the resulting detriment to the accused is irreparable.
The order is reversed.
Burke, P. J., and Jefferson, J., concurred.
Respondent’s petition for a hearing by the Supreme Court was denied May 6, 1964.
