And they took him away forthwith, a writhing, furious Thing, utterly transformed from the genial personality which had for so long swindled and outwitted a trusting public.

As the door closed upon them, Cleek turned to young Wilson and held out his hand.

"I'm sorry to have accused you as I did," he said softly, with a little smile, "but that is a policeman's way, you know. Strategy is part of the game—though it was a poor trick of mine to cause you additional pain. You must forgive me. I don't doubt the death of your father was a great shock, although you tried manfully to conceal the relationship. No doubt it was his wish—not yours."

A sudden transformation came over Wilson's pale, haggard face. It was like the sun shining after a heavy storm.

"You—knew?" he said, over and over again. "You knew? Oh, Mr. Cleek, now I can speak out at last. Father always made me promise to be silent, he—he wanted me to be a gentleman, and he'd spent every penny he possessed to get me well enough educated to enter the bank. He was mad for money, mad for anything which was going to better my position. And—and I was afraid when he told me about the notes, he might be tempted—Oh! It was dreadful of me, I know, to think of it, but I knew he doted upon me, I was afraid he might try and take one or two of them, hoping they wouldn't be missed out of so great an amount. You see we'd been in money difficulties and were still paying my college fees off after all this time. So I went back to keep watch with him—and found him dying—though how you knew—"

His voice trailed off into silence, and Cleek smiled kindly.

"By the identical shape of your hands, my boy. I never saw two pairs of hands so much alike in all my life. And then your agitation made me risk the guess.... What's that, Inspector? How was the murder committed, and what did this little rattler have to do with it? Well, quite simple. The snake was put in the safe with the notes, and a trail of aniseed—of which snakes are very fond, you know—laid from there to the foot of old Simmons. The safe door was left ajar—though in the half dusk the old man certainly never noticed it. I found all this out from those few words of Wilson's about 'the rope,' and from his having heard a reed-like sound. I had to do some hard thinking, I can tell you. When I went downstairs again, Mr. Narkom, after my magnifying glass, I turned down poor Simmons's sock and found the mark I expected—the snake had crawled up his leg and struck home.

"Why did I suspect Mr. Brent? Well, it was obvious almost from the very first, for he was so anxious to throw suspicion upon Mr. Barrington here, and Wilson—with Patterson thrown in for good measure. Then again it was certain that no one else would have been allowed into the vault by Simmons, much less to go to the safe itself, and open it with the keys. That he did go to the safe was apparent by the finger prints upon it, and as they too smelt of [aniseed], the whole thing began to look decidedly funny. The trail of aniseed led straight up to where Simmons lay, so I can only suppose that after Brent released the snake—the trail of course having been laid beforehand, when he was alone—Brent must have stood and waited until he saw it actually strike, and—How do I know that, Mr. Wilson? Well, he smoked a cigarette there, anyhow. The stub I found bore the same name as those in his box, and it was smoked identically the same way as a couple which lay in his ashtray.

"I could only conclude that he was waiting for something to happen, and as the snake struck, he grabbed up the bundle of notes, quite forgetting to close the safe-door, and rushed out of the vault. Ramagee was in the corridor outside, and probably whistled the snake back through the ventilating holes near the floor, instead of venturing near the body himself. You remember, you heard the sound of that pipe, Mr. Wilson? Ramagee probably made his escape while the Inspector was upstairs. Unfortunately for him, he ran right into Mr. George Barrington here, and when, as he tells me, he later told Brent about seeing Ramagee, well, the whole thing became as plain as a pikestaff."

"Yes," put in George Barrington, excitedly, taking up the tale in his weak, rather silly voice, "my step-father refused to believe me, and gave me £20 in notes to go away. I suppose he didn't notice they were some of the stolen ones. I changed one of them at the bank this morning, but I had no idea how important they were until I knocked into Mr.—Mr. Cleek here. And he made me come along with him."
