"Ho ho ho," chortled H.M., with a leer. "Charters has got it stuck in his throat; he can't go any farther; he can't tell you where you come in, Ken. But I will. You're goin' to do a spot of housebreaking."

I set down my empty glass, looked at H.M., and began to feel a trifle ill.

"Point's this," pursued H.M. obstinately, and pointed with a vast flipper. "If Hogenauer's on the level, he could get his two thousand quid. Oh, yes. We've made these little bargains before, though nobody ever whispers it to the police. I'd be willing to pay it out of my own pocket. But is be on the level? Son, there's something awful fishy about this whole business, and I smell the blood of an Englishman again. It's all wrong. There's somethin' rummy and devilish peepin' out of it, which we don't begin to understand. Therefore we got to begin to understand it. Therefore, you're goin' to bust into this beggar's house, and overhaul his papers if he's got any, and find out what the flickering lights mean when they whirl round the flower-pot. Got it?"

Charters cleared his throat. "Of course," he said, "I can't give you any official sanction.

"Exactly," I said, "so what if I'm caught? Damn it all, tomorrow I'm supposed to be married. Why don't you hire a professional burglar?"

"Because I couldn't protect a professional burglar," answered the Chief Constable rather snappishly, "and I can protect you. Besides, there will be no danger. Hogenauer is going to Bristol to-night, not later than by the eight o'clock train, and he won't be back until tomorrow. He was at Dr. Antrim's last night, and told Antrim that. As for the manservant, he's courting a girl in Torquay and won't be back until midnight at the earliest. You will have a couple of hours after dark — probably more-to make a thorough examination of an empty house." Then Charters grew uneasy, after the effervescence of the old days had subsided. "But it's damned irregular all the same," he grumbled. "I shouldn't blame you if you refused to go. Mind, Merrivale, this is your responsibility entirely. If anything should go wrong-"

I pointed out, with some heat, just whose responsibility it was. H.M. was soothing. "Looky here!" he added, with an air of inspiration, as though he were dangling a peppermint-stick in front of a child. He lumbered into the house and emerged with a small black satchel, rather like a doctor's medicine-case. From this he took a series of skeleton keys, or `twirlers' as we used to call them, a brace and bit, wedges, a forceps, and a glass-worker's diamond. Next came a clawshaped jemmy whose design was new to me, a small bottle of paraffin oil to use on the metal instruments, a pair of rubber gloves, and a very curious tiny bottle which glowed inside like a cluster of fireflies.

"The Compleat Burglar," observed H.M. with ghoulish relish. "Don't it fire your blood, Ken? This is a telescopic jemmy; finest thing made; a yard long extended, and it's got a powerful leverage. This bottle of phosphorus is much better than a flashlight. Flashlights have a habit of flyin' all over the place, and coppers see them through the window. This can't be seen, and there's enough light for any honest purpose. I say, Charters, we'd better put in some stickin'plaster for him in case he has to cut a pane out of a window. You take my advice, Ken, and try the scullery window first; that's the most vulnerable part of any house. You're wearin' a dark-blue suit, and that's all right…"

"Just a minute," I interposed. "What I want to know is, why the unnecessary camouflage? Instead of saying, `absolute burning imperative that you be butler,' why didn't you say burglar? What has my role as Robert Butler got to do with this?"

H.M. did not roar. He remained blinking steadily at me, turning over the jemmy in his hand.
