This is an appeal (1) from Shuman’s convictions on June 24, 1982, in a jury-waived trial in the Superior Court of (a) arson of a building (G. L. c. 266, § 2) and (b) burning the same building with intent to defraud the insurer (G. L. c. 266, § 10), and (2) from the denial of his motion for a new trial. The fire was reported to the fire department about 11:35 p.m. on March 24, 1981. There was strong evidence that it had been set on the vacant third floor of a commercial building at 32 Hampden Street, Sрringfield (the locus) owned by Dr. Harvey Grant. Shuman, a tenant, maintained a hairdressing salon on the second floor. A sprinkler system had contained the fire to the third floor. Shuman’s salon was not significantly damaged by fire, but water from the sprinkler system caused considerable injury to it.
1. Shuman first contends that the trial judge should have granted his motions, made both at the close of the Commonwealth’s case and at the close of all the evidence, for required findings of not guilty. The evidence was largely circumstantial. On particular issues much of the evidence was conflicting. We conclude that the evidence, viewed in its aspect most favorable to the Commonwealth’s position, taken with all permissible inferences from that evidence, was sufficient to allow the trial judge to conclude, beyond a reasonable doubt, that Shuman had set the fire or caused it to be set. See
Commonwealth
v.
Kelley,
(a) It does not seem seriously to be disputed, in the face of persuasive expert testimony, that the fire had been set on the third floor intentionally with the aid of an accelerant. One expert estimated that three to four gallons of gasoline had been used. No containers for the accelerant used were found, indicating that these had been removed by the person setting the fire. It could be found that the sprinkler system *443 on the third floor (and the prompt arrival of the fire department) had prevented the whole building from being consumed. The attempt to burn the building, in one expert’s opinion, “was poorly done; very unprofessional.”
(b) When the firemen arrived, they had to break in the front door leading to the stairs to the second and upper floors. They found a door to the vacant third floor open. All other entrances to the upper floors were locked. A third floor window, accessible from a somewhat shaky fire escape with bolts to the west side of the building missing, was closed, badly warped, and difficult to open. A security device had been recently removed from that window.
(c) There was an alarm system on the second floor which was subject to two separate controls, each also subject to use of a special key. The first was a master control switch located in a back room. The second (dependent for its operation upon the first master switch being in the “on” or “night” position) was outside an entrance door to the second floor. The master control, the judge could have found, was usually left in the “night” or “on” position, with the second, outside control used to activate the alarm at the end of each day. When the fire department arrived, the second switch had been activated but the master switch was in the “off” position. The alarm of the tenant оn the first floor was sounding. Shuman’s second floor alarm was not sounding. Tested promptly after the fire, the second floor alarm system was found to be operating properly if duly activated. 1
(d) There was conflicting evidence about the number of keys to the upper floors which had been distributed. The judge would have been warranted in finding that the number was limited. The upper floors could each be rеached *444 from the first and second floors by a very slow moving elevator, found after the fire near or above the second floor. There was evidence that it was operable in March, 1981.
(e) There was evidence that Shuman at a bar in Boston in February, 1981, asked a friend and former employee, Richard O’Zemko, when as many as fifteen other hairdressers were at or near the same tаble, “could anybody burn my business or my building down or something to that effect.” O’Zemko, on the stand, claimed that the statement attributed to him had been taken out of context and that he had signed a written statement about Shuman’s inquiry under police threats and in the confusion of being placed under arrest. On the stand, O’Zemko appears to have been embarrassed and, perhaps, evasive. There was testimony of others, supposed to have been present, that they had not heard the statement. At the meeting in the bar, Shuman also, in reply to a suggestion that it would be nice if the group of hairdressers could work together again, said (perhaps jokingly) “the only possible way we could probably work together again is if my building burned down or something to that effect.” This statement may have been a different vеrsion of O’Zemko’s account of Shuman’s inquiry mentioned above. Another statement (made at some uncertain time) was attributed to Shuman by his landlord’s brother, Albert Grant, a caretaker at the locus, that Shuman was “going to take care of this building for” the brother and Albert. Shuman, in effect, denied making each of these statements. 2
(f) There was somewhat confused and confusing testimony concerning the amount оf Shuman’s investment in fixtures and improvements for his hairdressing establishment. It could have been found on the evidence that his aggregate investment amounted to around $105,000. Shuman carried $150,000 of insurance (including fire) on the premises, under *445 a policy due to expire one week after the fire. This policy was not introduced in evidence. See part 2 of this opinion, infra.
(g) There was conflicting evidence abоut Shuman’s financial condition at the time of the fire. A loan (originally $60,000, with a balance of about $30,000 due at the time of the fire) had been made to Shuman by a Springfield bank. Eighty percent of this loan was backed by a Small Business Administration (S.B.A.) guaranty. At the request of the bank, this loan was taken over by S.B.A., but was up to date at the time of trial. After a motorcycle accident in the late spring or early summer of 1980, Shuman оbtained a moratorium on the payment of interest on this loan. One very small supplier was insisting on cash payments for his deliveries to Shuman’s salon. Shuman owed some $20,000 of back Federal income taxes, which he was paying by agreement with the Internal Revenue Service, at the rate of $500 each month. His property was subject to a $3,900 tax lien. His rent was not paid promptly nor were small bank loans. There was evidence that his business was for sale. Shuman appears to have disclosed his debts frankly when asked about them by the police. Shuman could have been found to have been separated from his wife and paying her $100 per week. He had lived with a “girlfriend” after November, 1980. She was with him on the night of the fire. A woman, later his partner, described Shuman as “an artist and not a businessman.”
(h) Shuman was mаking substantial sums from representing various firms for giving hairdressing demonstrations, but the business had been hurt when Shuman had been injured in the 1980 motorcycle accident. He had the prospect of some contribution to the business by the woman with whom, after the fire, he had gone into a hairdressing “partnership.” Nevertheless, in a series of letters to the Springfield bank, written in late 1980 and early 1981, he had sought to renegotiate and increase his S.B.A. guaranteed loan by representing his business as being in a very difficult situation. Shuman admitted that these letters contained misrepresen *446 tations of his financial condition. The aggregate evidence could be viewed by a rational trier of the facts, here an experienced trial judge, as amounting to proof that Shuman would gain benefit from collecting the insurance proceeds of a total loss. He then would have been able to pay off his S.B.A. loan and his back tax indebtedness, thus avoiding interest and possible tax penalties. He presumably could move into other less elaborate quarters and still operate a similar enterprise.
The evidence was not as conclusive in all respects and on particular issues as in some other cases involving proof of responsibility for an incendiary fire. See e.g.,
Commonwealth
v.
Bader,
The evidence does not show Shuman to have had exclusive access to the third floor of the locus. He possessed, however, one of a limited number of keys to the front door of the locus and to the second floor. The one unlocked window on the third floor could have had its safety block pried off only from the inside. The quantity of gasoline used as an accelerant would have required a substantial container perhaps not easily carried up a shaky fire escape even at night without being observed. That Shuman’s master alarm control was in an “off” position was unusual. He had one of the few keys to that control, which, of course, could have been turned off at any time by him or by another. Shuman, in a somewhat stringent financial condition, had аn obvious motive to collect insurance. His insurance was ample and perhaps somewhat excessive. It was about to expire. His denials involved questions of his credibility which was badly shaken by his admitted misrepresentations in trying to renegotiate his S.B.A. guaranteed loans. Although no one of the “circumstances . . . alone” might have been “enough to convict” him, they “combine to form a fabric of proof . . . sufficient to warrant the . . . [judge’s] finding beyond a reasonable doubt.” See
Commonwealth
v.
Rojas,
2. Although the insurance policy was not placed in evidence, there was ample testimony of the insurance upon Shuman’s interest in the locus and its fixtures and contents frоm an employee of the insurer, admitted without objection. There was no subsequent motion to strike that testimony. The witness described the policy, its face amount, scope of coverage, and expiration date. Shuman himself testified that he made claim under his insurance for water damage. His own insurance broker testified to its existence. The failure to object to the testimony as héаrsay when it was
*448
offered precludes any consideration now of its admissibility.
Commonwealth
v.
Gallo,
3. Shuman sought a new trial, among other reasons, to introduce evidence of a polygraph test administered by a private examiner. The test purported to show that Shuman was truthful in denying that he set or caused the fire at the locus. The judge denied the motion for a new trial and also a motion to consider the polygraph test, in part because “the test was not taken in accordance with the guidelines set out in
Commonwealth
v. A
Juvenile,”
*449
4. Shuman contends that he cannot be convicted of, and sentenced for, arson under G. L. c. 266, § 2,
3
and also of and for arson with intent to defraud an insurancе company under c. 266, § 10,
4
on the ground that such convictions are duplicitous. In
Commonwealth
v.
Crocker,
The trial judge upon the conviction under § 2 imposed a sentence of incarceration for two years in a house of correction. Under § 10, he imposed a more severe sentence to M.C.I. Walрole for not more than five years nor less than three years, suspended, with probation for three years from and after the completion of the sentence under § 2. These sentences doubtless were imposed because the trial judge thought the two convictions were not duplicitous. We do not attempt to resolve the confusion caused by these sentences.
We recognize, of course, the principle stated in
Commonwealth
v.
Jones,
382 Mass, at 395, that when “consеcutive sentences on duplicitous charges have been imposed, the remedy ordered . . . has been to vacate both the conviction and sentence on the lesser-included offense, and to affirm that on the more serious offense.” It may be that, because the Legislature has permitted a maximum sentence under § 2 greater than that allowed under § 10, the former should be regarded as the more serious offense. Nevertheless, in
Kuklis
v.
Commonwealth,
So ordered.
Notes
Cindy Ferns, a belly-dance teacher, taught a class at night in Shuman’s hairdressing salon. On the night of the fire she left the second floor about 9:15 p.m., making sure that the outside alarm control (but not the master control, which she did not check) was activated. She had been told that evening by Shuman, when he departed about 7:00 p.m., that she would have to start paying rent for using his second floor salon, which theretofore she had used without charge, perhaps because use of the salon “was a swap for belly dancing lessons for” Shuman’s wife.
There was an affidavit filed by the landlord, in connection with the motion for a new trial, that Shuman in fact performed some custodial and tеnant-relations services in connection with the locus. The quoted inquiry in the first sentence of subpar. (e) above is the way O’Zemko concluded his direct testimony.
Section 2, as appearing in St. 1948, c. 43, § 2, reads in part:
“Whoever wilfully and maliciously sets fire to, burns, or causes to be burned, or whoever aids, counsels or procures the burning of . . . any building or structure or contents thereof, not included or described in the preceding section [refеrring essentially to dwellings and residential buildings], whether the same is the property of himself or of another and whether occupied, unoccupied or vacant, shall be punished by imprisonment in the state prison for not more than ten years, or by imprisonment in a jail or house of correction for not more than two and one half years” (emphasis supplied).
Section 10, as appearing in St. 1932, c. 192, § 7, reads:
“Whoever, wilfully and with intent to defraud or injure the insurer, sets fire to, or attempts to set fire to, or whoever causes to be burned, or whoever aids, counsels or procures the burning of, a building, or any goods, wares, merchandise or other chattels, belonging to himself or another, and which are at the time insured against loss or damage by fire, shall be punished by imprisonment in the state prison for not more than five years or in a jail or house of correction for not more than two аnd one half years” (emphasis supplied).
See the discussion in Nolan, Criminal Law §§ 424-426 (1976 & Supp. 1983); Perkins, Criminal Law 216-230 (2d ed. 1969); Model Penal Code, § 220.1 (Official Code 1980); Smith, Criminal Practice and Procedure §§ 1056-1058, 1320 (2d ed. 1983). Nothing in these discussions suggests that a statute like § 2 requires proof of any element not necessarily or inferentially established by proof of the essential elements of a statute like § 10. We perceive no such suggestion in the
Niziolek
case,
