Graham Patterson, in the agony of that last convulsion, had nearly slipped off the seat, so that, with a very little, he would be on the floor. His nephew, who hitherto had not for a moment lost his presence of mind, and who kept it then, was at a loss. Would such an attitude be recognised as proper for a suicide? Would, that is, a doctor--any doctor--be prepared to assert that a man who had killed himself with potassium cyanide might, under the circumstances, quite conceivably die in such an attitude, or assume it after death? To Rodney's supernaturally keen vision there were trifles about his uncle's appearance which scarcely marked this as inevitably a case of suicide. The collar was a little crumpled; the tie a little disarranged; he even fancied that there were prints of his fingers on the skin of the throat. He was conscious that he had gripped him with great force--perhaps a little clumsily; he certainly ought to have avoided contact with the collar and the tie, but no doubt the prints would wear off. Indeed, as he bent closer he was not sure that they did not exist only in his imagination; the light was not good; he could not be certain. With dexterous fingers he smoothed the collar, he rearranged the tie--so deftly that he felt convinced that no one would notice that anything had been wrong with him. He raised the body a little, so that it was in what seemed to him to be a more natural position, on the edge of the seat; he felt that it would look better. He was surprised to find how heavy his uncle was--it required quite an effort on his part to lift him. He turned the contents of the silver box on to his hand. There were seven tiny lozenges. He returned three to the box, and laid it on the seat; the other four he placed beside it. Taking an envelope out of an inner pocket of his jacket, he tore off a corner. In it he placed the four tabloids, carefully folded it, and put it in his waistcoat pocket. Then he balanced the cap of the box on the arm of the seat beside his uncle; the box itself he placed between the fingers of his uncle's left hand, with--in it--the other three tabloids. So tightly were the fingers clenched that Rodney had to use force to open them sufficiently to enable him to insert the box. Then, seating himself opposite, he looked his uncle carefully over with an artist's eye for detail. In his present attitude, with that open box with its tell-tale contents held tightly between his stiffened fingers, it seemed to Rodney that a coroner would be bound to instruct his jury that suicide was the only possible explanation of Graham Patterson's death. Having satisfied himself on which point, he withdrew to the opposite end of the carriage, being, in spite of himself, conscious of a feeling that the dead man's too immediate neighbourhood was not a thing to be desired.
