It required no little hardihood to challenge Masterman Throgton at billiards. His reputation at his club as a cool, determined player was surpassed by few. Throgton had been known to run nine, ten, and even twelve at a break. It was not unusual for him to drive his ball clear off the table. His keen eye told him infallibly where each of the three balls was; instinctively he knew which to shoot with.
In Kent, however, he had no mean adversary. The young reporter, though he had never played before, had studied his book to some purpose. His strategy was admirable. Keeping his ball well under the shelter of the cushion, he eluded every stroke of his adversary, and in his turn caused his ball to leap or dart across the table with such speed as to bury itself in the pocket at the side.
The score advanced rapidly, both players standing precisely equal. At the end of the first half-hour it stood at ten all. Throgton, a grim look upon his face, had settled down to work, playing with one knee on the table. Kent, calm but alive with excitement, leaned well forward to his stroke, his eye held within an inch of the ball.
At fifteen they were still even. Throgton with a sudden effort forced a break of three; but Kent rallied and in another twenty minutes they were even again at nineteen all.
But it was soon clear that Transome Kent had something else in mind than to win the game. Presently his opportunity came. With a masterly stroke, such as few trained players could use, he had potted his adversary's ball. The red ball was left over the very jaws of the pocket. The white was in the centre.
Kent looked into Throgton's face.
The balls were standing in the very same position on the table as on the night of the murder.
"I did that on purpose," said Kent quietly.
"What do you mean?" asked Throgton.
"The position of those balls," said Kent. "Mr. Throgton, come into the library. I have something to say to you. You know already what it is."
