"Ours were like ever so many little tiny rooms," said Cazalet, "where I couldn't stand nearly upright even as a small boy without giving my head a crack against the ground floors. They led into one another by a lot of little manholes—tight fits even for a boy, but nearly fatal to the boss policeman yesterday! I used to get in through one with a door, at the back of a slab in the cellars where they used to keep empty bottles; they keep 'em there still, because that's how I led my party out last night."

Cazalet's little gift of description was not ordered by an equal sense of selection. Hilton Toye, edging in his word in a pause for a gulp of coffee, said he guessed he visualized—but just where had those missing things been found?

"Three or four compartments from the first one under the library," said Cazalet.

"Did you find them?"

"Well, I kicked against the truncheon, but Drinkwater dug it up. The watch and keys were with it."

"Say, were they buried?"

"Only in the loose rubble and brick-dusty stuff that you get in foundations."

"Say, that's bad! That murderer must have known something, or else it's a bully fluke in his favor."
