United States government," Trant motioned to the slight, dark man who was the fourth member of the party, "I have been able to fix upon four men, one of whom, I feel absolutely certain, shot and killed young Newberry through the window of the billiard-room that night. Inspector Walker has had all four arrested and brought here. Mr. Ferris's experience and thorough knowledge enabled me to lay my hands on them much more easily than I had feared, though I was able to go to him with information which would have made their detection almost certain sooner or later."
"You mean information you got at the house?" asked Siler, less derisively, as he caught the attentive attitude of the inspector.
"Just so, Siler; and it was as much at your disposal as mine," Trant replied. "It seemed to mean nothing to you that Walter Newberry knew the hour at which he was to die—which made it seem more like an execution than a murder; or that in his terror he raved that 'he would not do it—that they could not make him do it'—plainly meaning commit suicide. Perhaps you don't know that it is an Oriental custom, under certain conditions, to allow a man who has been sentenced to death, the alternative of carrying out the decree upon himself before a certain day and hour that has been decided upon. But certainly his ravings, as told us by his wife, ought to have given you a clew, if you had heard only that sentence which she believed an injunction not to sing loudly, but which was in reality a name—Sing lo!"
