“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. IV 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.
