“No, sir, not when he come he hadn’t; he was working his own motoring car himself, and what luggage he had, let me see: there was his lantern and this box of slides inside the carriage, which I helped him into the Chapel and out of it myself with it, if only I’d knowed! And as he drove away under the big yew tree by the monument, I see the long white bundle laying on the top of the coach, what I didn’t notice when he drove up. But he set in front, sir, and only the boxes inside behind him. And do you reely think, sir, as his name weren’t Henderson at all? Oh, dear me, what a dreadful thing! Why, fancy what trouble it might bring to a innocent person that might never have set foot in the place but for that!”

They left Mrs Porter in tears. On the way home there was much discussion as to the best means of keeping watch upon possible sales. What Henderson-Homberger (for there could be no real doubt of the identity) had done was, obviously, to bring down the requisite number of folio Prayer-Books—disused copies from college chapels and the like, bought ostensibly for the sake of the bindings, which were superficially like enough to the old ones—and to substitute them at his leisure for the genuine articles. A week had now passed without any public notice being taken of the theft. He would take a little time himself to find out about the rarity of the books, and would ultimately, no doubt, “place” them cautiously. Between them, Davidson and Witham were in a position to know a good deal of what was passing in the book-world, and they could map out the ground pretty completely. A weak point with them at the moment was that neither of them knew under what other name or names Henderson-Homberger carried on business. But there are ways of solving these problems.

And yet all this planning proved unnecessary.

We are transported to a London office on this same 25th of April. We find there, within closed doors, late in the day, two police inspectors, a commissionaire, and a youthful clerk. The two latter, both rather pale and shaky in appearance, are sitting on chairs and being questioned.

“How long do you say you’ve been in this Mr Poschwitz’s employment? Six months? And what was his business? Attended sales in various parts and brought home parcels of books. Did he keep a shop anywhere? No? Disposed of ’em here and there, and sometimes to private collectors. Right. Now then, when did he go out last? Rather better than a week ago? Tell you where he was going? No? Said he was going to start next day from his private residence, and shouldn’t be at the office—that’s here, eh?—before two days; you was to attend as usual. Where is his private residence? Oh, that’s the address, Norwood way; I see. Any family? Not in this country? Now, then, what account do you give of what’s happened since he came back? Came back on the Tuesday, did he? and this is the Saturday. Bring any books? One package; where is it? In the safe? You got the key? No, to be sure, it’s open, of course. How did he seem when he got back—cheerful? Well, but how do you mean—curious? Thought he might be in for an illness: he said that, did he? Odd smell got in his nose, couldn’t get rid of it; told you to let him know who wanted to see him before you let ’em in? That wasn’t usual with him? Much the same all Wednesday, Thursday, Friday. Out a good deal; said he was going to the British Museum. Often went there to make inquiries in the way of his business. Walked up and down a lot in the office when he was in. Anyone call in on those days? Mostly when he was out. Anyone find him in? Oh, Mr Collinson? Who’s Mr Collinson? An old customer; know his address? All right, give it us afterwards. Well, now, what about this morning? You left Mr Poschwitz’s here at twelve and went home. Anybody see you? Commissionaire, you did? Remained at home till summoned here. Very well.

“Now, commissionaire; we have your name—Watkins, eh? Very well, make your statement; don’t go too quick, so as we can get it down.”

“I was on duty ’ere later than usual, Mr Potwitch ’aving asked me to remain on, and ordered his lunching to be sent in, which came as ordered. I was in the lobby from eleven-thirty on, and see Mr Bligh [the clerk] leave at about twelve. After that no one come in at all except Mr Potwitch’s lunching come at one o’clock and the man left in five minutes’ time. Towards the afternoon I became tired of waitin’ and I come upstairs to this first floor. The outer door what lead to the orfice stood open, and I come up to the plate-glass door here. Mr Potwitch he was standing behind the table smoking a cigar, and he laid it down on the mantelpiece and felt in his trouser pockets and took out a key and went across to the safe. And I knocked on the glass, thinkin’ to see if he wanted me to come and take away his tray; but he didn’t take no notice, bein’ engaged with the safe door. Then he got it open and stooped down and seemed to be lifting up a package off of the floor of the safe. And then, sir, I see what looked to be like a great roll of old shabby white flannel, about four to five feet high, fall for’ards out of the inside of the safe right against Mr Potwitch’s shoulder as he was stooping over; and Mr Potwitch, he raised himself up as it were, resting his hands on the package, and gave a exclamation. And I can’t hardly expect you should take what I says, but as true as I stand here I see this roll had a kind of a face in the upper end of it, sir. You can’t be more surprised than what I was, I can assure you, and I’ve seen a lot in me time. Yes, I can describe it if you wish it, sir; it was very much the same as this wall here in colour [the wall had an earth-coloured distemper] and it had a bit of a band tied round underneath. And the eyes, well they was dry-like, and much as if there was two big spiders’ bodies in the holes. Hair? no, I don’t know as there was much hair to be seen; the flannel-stuff was over the top of the ’ead. I’m very sure it warn’t what it should have been. No, I only see it in a flash, but I took it in like a photograft—wish I hadn’t. Yes, sir, it fell right over on to Mr Potwitch’s shoulder, and this face hid in his neck,—yes, sir, about where the injury was,—more like a ferret going for a rabbit than anythink else; and he rolled over, and of course I tried to get in at the door; but as you know, sir, it were locked on the inside, and all I could do, I rung up everyone, and the surgeon come, and the police and you gentlemen, and you know as much as what I do. If you won’t be requirin’ me any more to-day I’d be glad to be getting off home; it’s shook me up more than I thought for.”

“Well,” said one of the inspectors, when they were left alone; and “Well?” said the other inspector; and, after a pause, “What’s the surgeon’s report again? You’ve got it there. Yes. Effect on the blood like the worst kind of snake-bite; death almost instantaneous. I’m glad of that, for his sake; he was a nasty sight. No case for detaining this man Watkins, anyway; we know all about him. And what about this safe, now? We’d better go over it again; and, by the way, we haven’t opened that package he was busy with when he died.”

“Well, handle it careful,” said the other; “there might be this snake in it, for what you know. Get a light into the corners of the place, too. Well, there’s room for a shortish person to stand up in; but what about ventilation?”
