"I thought it would be," he returned. "A momentary ray of light illumined those twelve good men, and they agreed that it could not be suicide." "Of course it might have been an accident," I said, "but I don't think the evidence justified the verdict." "A strange case, Wigan, and very difficult because it seems so easy. There are one or two curious points to begin with. Practically no one in Riversmouth knew Dr. Smith. He seldom went outside his own grounds. It is reasonable to assume, therefore, that he was a peculiar man. He bought a boat because it happened to be a bargain, his wife thinks, suggesting that spending his money in this way to no purpose was a hobby with him; yet we hear nothing of any other bargains to support the idea. Until we have evidence to the contrary, then, we may assume that some idea was in his mind when he bought the boat. He didn't forget all about its existence, remember, because twice during the summer he sent his assistant out in it, and the assistant pronounces it a very good boat and easy to manage. Now, what possessed Dr. Smith to go for a sail on that particular day and at that time of the day? He was certainly not an ardent yachtsman." "Since he was peculiar, it is naturally difficult to account for his actions," I said. "A possible explanation," Quarles returned. "He may always have had the idea of suicide at the back of his brain," said Zena. "It may have been in his mind when he bought the boat. If one lives near the sea and contemplates suicide, it would be natural to choose drowning." "There is much in that argument," said the professor. "It was in my mind when I said it was curious no body was washed up with the wreckage," said Zena. "That remark of yours set me thinking," Quarles went on. "I wondered, Wigan, whether the doctor was on board the boat when she capsized, or whatever it was that happened to her. Now my wonder is increased. The waves had battered the boat to pieces, but when the body is found, caught on the rocks, it is comparatively uninjured." "Doubtless it had been carried farther out to sea," I said. "But it had to come ashore, and the weather was stormy the whole time. It could hardly have escaped altogether. There was something else to raise doubt. There were rents in the coat, rents which were all much alike, and a curious bulge in the collar of the coat. These things gave me a definite theory. The doctor was not in the boat, nor had he committed suicide." "Are you suggesting murder?" "I am." "At the inquest the doctor distinctly said that there were no marks on the body to suggest he had been the victim of foul play. He was drowned; he was not killed first and put in the water afterward."
