"Well, that is what we are here to find out. It has nothing whatever to do with our client, so far as I can read the situation. It is something connected with the man he murdered—the man who may have been his confederate in crime. There is some guilty secret in the room. That is how I read it. At first I thought our friend might have something in his collection more valuable than he knew—something worth the attention of a big criminal. But the fact that Rodger Prescott of evil memory inhabited these rooms points to some deeper reason. Well, Watson, we can but possess our souls in patience and see what the hour may bring."
That hour was not long in striking. We crouched closer in the shadow as we heard the outer door open and shut. Then came the sharp, metallic snap of a key, and the American was in the room. He closed the door softly behind him, took a sharp glance around him to see that all was safe, threw off his overcoat, and walked up to the central table with the brisk manner of one who knows exactly what he has to do and how to do it. He pushed the table to one side, tore up the square of carpet on which it rested, rolled it completely back, and then, drawing a jemmy from his inside pocket, he knelt down and worked vigorously upon the floor. Presently we heard the sound of sliding boards, and an instant later a square had opened in the planks. Killer Evans struck a match, lit a stump of candle, and vanished from our view.
Clearly our moment had come. Holmes touched my wrist as a signal, and together we stole across to the open trapdoor. Gently as we moved, however, the old floor must have creaked under our feet, for the head of our American, peering anxiously round, emerged suddenly from the open space. His face turned upon us with a glare of baffled rage, which gradually softened into a rather shamefaced grin as he realized that two pistols were pointed at his head.
"Well, well!" said he, coolly, as he scrambled to the surface. "I guess you have been one too many for me, Mr. Holmes. Saw through my game, I suppose, and played me for a sucker from the first. Well, sir, I hand it to you; you have me beat and——"
In an instant he had whisked out a revolver from his breast and had fired two shots. I felt a sudden hot sear as if a red-hot iron had been pressed to my thigh. There was a crash as Holmes's pistol came down on the man's head. I had a vision of him sprawling upon the floor with blood running down his face while Holmes rummaged him for weapons. Then my friend's wiry arms were round me and he was leading me to a chair.
"You're not hurt, Watson? For God's sake, say that you are not hurt!"
It was worth a wound—it was worth many wounds—to know the depth of loyalty and love which lay behind that cold mask. The clear, hard eyes were dimmed for a moment, and the firm lips were shaking. For the one and only time I caught a glimpse of a great heart as well as of a great brain. All my years of humble but single-minded service culminated in that moment of revelation.
"It's nothing, Holmes. It's a mere scratch."
He had ripped up my trousers with his pocket-knife.
"You are right," he cried, with an immense sigh of relief. "It is quite superficial." His face set like flint as he glared at our prisoner, who was sitting up with a dazed face. "By the Lord, it is as well for you. If you had killed Watson, you would not have got out of this room alive. Now, sir, what have you to say for yourself?"
