"One of the very closest," replied Pett. "Yes, you may say that, sir."

"Not likely to let things out, I suppose?" continued Brereton.

"Not he! He was a regular old steel trap, Kitely was—shut tight!" said Pett.

"And—I suppose you've no theory, no idea of your own about his murder?" asked Brereton, who was watching the little man closely. "Have you formed any ideas or theories?"

Pett half-closed his eyes as he turned them on his questioner.

"Too early!" he replied, with a shake of his head. "Much too early. I shall—in due course. Meantime, there's another little commission I have to discharge, and I may as well do it at once. There are two or three trifling bequests in this will, gentlemen—one of 'em's to you, Mr. Bent. It wasn't in the original will—that was made before Kitely came to these parts. It's in a codicil—made when I came down here a few weeks ago, on the only visit I ever paid to the old gentleman. He desired, in case of his death, to leave you something—said you'd been very friendly to him."

"Very good of him, I'm sure," said Bent with a glance of surprise. "I'm rather astonished to hear of it, though."

"Oh, it's nothing much," remarked Pett, with a laugh as he drew from the brief bag what looked like an old quarto account book, fastened by a brass clasp. "It's a scrap-book that the old man kept—a sort of album in which he pasted up all sorts of odds and ends. He thought you'd find 'em interesting. And knowing of this bequest, sir, I thought I'd bring the book down. You might just give me a formal receipt for its delivery, Mr. Bent."

Bent took his curious legacy and led Mr. Pett away to a writing-desk to dictate a former of receipt. And as they turned away, the superintendent signed to Brereton to step into a corner of the room with him.

"You know what you said about that electric torch notion this afternoon, sir?" he whispered. "Well, after you left me, I just made an inquiry—absolutely secret, you know—myself. I went to Rellit, the ironmonger—I knew that if such things had ever come into the town, it 'ud be through him, for he's the only man that's at all up-to-date. And—I heard more than I expected to hear!"
