"Aye, man, and who could there be, wi' a crest and monogram on his kerchief, that 'ud murder yon man the secret way he has?" he retorted, answering my incredulous look with one of triumph. "Tell me that, my laddie! I'm telling you, Middlebrook, that this was no common murder any more than the murder of the man's own brother down yonder at Saltash, which is a Cornish riverside place, and a good four or five hundred miles away, was a common, ordinary crime! Man! we're living in the very midst of a mystery—and that there's bloody-minded, aye, and bloody-handed men, maybe within our gates, but surely close by us, is as certain to me as that I'm looking at you!"
"I thought you believed that Salter Quick's murderer was miles away before ever Salter Quick was cold?" I observed.
"I did—and I've changed my mind," he answered. "I'm not thinking it any more, and all the less since I was robbed of my venerable pocket-book, with those two exhibits o' the crime in its wame. The murderer is about! and though he mayn't have thought to get his handkerchief, he may have hoped that he'd secure some result o' my labours in the photographic line."
"Mr. Cazalette!" said I, "what were the results of your labours? I don't suppose that the print which was in your pocket-book was the only one you possess?"
"You're right there," he replied. "It wasn't. If the thief thought he was securing something unique, he was mistaken. But—I didn't want him, or anybody, to get hold of even one print, for as sure as we're living men, Middlebrook, what was on the inside of that lid was—a key to something!"
"You forget that the tobacco-box itself has been stolen from the police's keeping," I reminded him.
"And I don't forget anything of the sort," he retorted. "And the fact you've mentioned makes me all the more assured, my man, that what I say is correct! There's him, or there's them—in all likelihood it's the plural—that's uncommonly anxious, feverishly anxious, to get hold of that key that I suspicion. What were Salter Quick's pockets turned out for? What were the man's clothes slashed and hacked for? Why did whoever slew Noah Quick at Saltash treat the man in similar fashion? It wasn't money the two men were murdered for!—no, it was for information, a secret! Or, as I put it before, the key to something."
"And you believe, really and truly, that this key is in the marks or scratches or whatever they are on the lid of the tobacco-box?" I asked.
"Aye, I do!" he exclaimed. "And what's more, Middlebrook, I believe I'm a doited old fool! If I'd contrived to get a good, careful, penetrating look at that box, without saying anything to the police, I should ha' shown some common-sense. But like the blithering old idiot that I am, I spoke my thoughts aloud before a company, and I made a present of an idea to these miscreants. Until I said what I did, the murderous gang that knifed yon two men hadn't a notion that Salter Quick carried a key in his tobacco-box! Now—they know."
"You don't mean to suggest that any of the murderers were present when you asked permission to photograph the box!" I exclaimed. "Impossible!"
