His jaw dropped in dismay, but recovering himself instantly he put up a fairly good fight.

“It is strange, Mr. Lohengrin,” said I, “that in the three years I have been here I've never seen you before.”

“I've been very quiet,” he said. “Fact is, I have had my reasons, Mr. Holmes, for preferring the life of a hermit. A youthful indiscretion, sir, has made me fear to face the world. There was nothing wrong about it, save that it was a folly, and I have been anxious in these days of newspapers to avoid any possible revival of what might in some eyes seem scandalous.”

I felt sorry for him, but my duty was clear. Here was my man—but how to gain direct proof was still beyond me. No further admissions could be got out of him, and we soon parted.

Two days later the lady called and again I reported progress.

“It needs but one thing, madame, to convince me that I have found your husband,” said I. “I have found a man who might be connected with swan's-down, from whose luxuriant curls might have come this tow-colored lock, and who might have worn the silver-tinsel tights—yet it is all MIGHT and no certainty.”

“I will bring my small brother's bugle and the tin sword,” said she. “The sword has certain properties which may induce him to confess. My brother tells me that if he simply shakes it at a cat the cat falls dead.”

“Do so,” said I, “and I will try it on him. If he recognizes the sword and remembers its properties when I attempt to brandish it at him, he'll be forced to confess, though it would be awkward if he is the wrong man and the sword should work on him as it does on the cat.”

The next day I was in possession of the famous toy. It was not very long, and rather more suggestive of a pancake-turner than a sword, but it was a terror. I tested its qualities on a swarm of gnats in my room, and the moment I shook it at them they fluttered to the ground as dead as door-nails.

“I'll have to be careful of this weapon,” I thought. “It would be terrible if I should brandish it at a motor-man trying to get one of the Gehenna Traction Company's cable-cars to stop and he should drop dead at his post.”
