Mr. Marsh was leaning his elbows on the balcony railing and facing his audience as he explained his conviction that the captain had intended to keep him out. "I assure you," he was saying, and apparently he was directing his remarks at someone who now heard the tale for the first time; "I assure you, when I pushed the door and saw the man's shoulder, it moved. I mean it actually quivered, apart from my movement of the door. It gave me a very peculiar sensation, because when I spoke, there was no answer. Only a quiver. And another thing. When I finally did shove the door open and so shoved the captain over, the noise was not the noise of a dead inert body, if you understand me. Not at all. It sounded as though he had broken his fall somewhat! I can assure you----" Mr. Marsh had enjoyed an excellent education in England. He had the average Englishman's faculty of expressing himself in excellent commonplaces so that every other Englishman knew exactly what he meant. But his hearers on this occasion were not all Englishmen, and suddenly out of the dusk of the corner came a voice speaking English but not of England at all. Mr. Spokesly, standing a short distance off, was startled at the full-throated brazen clang of it booming through the obscurity of the vast chamber. It was a voice eloquent of youth and impudent virile good-humour, a voice with a strange harsh under-twang which the speaker's ancestors had brought out of central Asia, where they had bawled barbaric war-songs across the frozen spaces. "Broke his what? I don't understand what you mean," said the voice, and a fair-haired young man in a gray uniform, a short, thick golden moustache on his lip, came up suddenly out of the gloom into the radiance of the candles and began to stride to and fro. The interruption was trivial, yet it gave the key to the young man's character, courageous, cultured, precise, and impatient of inferior minds. "His fall," explained Mr. Marsh politely. "The point is, I believe he was alive almost up to the moment, you know, of our entry. He even moved slightly as I stepped in--a sort of last gasp. I even heard something of that nature. A sigh. Good evening, gentlemen." The last words were addressed to Mr. Spokesly and his friend in the Public Debt, who crossed the path of the young man striding up and down and were introduced to the company. "You can corroborate what I say," said Mr. Marsh. "You know I mentioned it at the time--a sort of sigh?" "What is a sigh, or a moment, for that matter, more or less?" demanded the young man striding up and down. "To me there is something much more important in his motive. Why did this captain of yours end himself? This is a question important to science. I am a student of Lombroso and Molle and the Englishman Ellis. Was this man epileptic? Did he have delusions of grandeur?"
