"And what is this?" asked Thorndyke, pointing to the open cigarette.
"Same stuff, undoubtedly," replied the inspector.
"And now let us see his cigarette papers," said Thorndyke.
The little book, or rather packet—for it consisted of separated papers—was produced from the officer's pocket and a sample paper abstracted. Thorndyke laid the half-burnt paper beside it, and the inspector, having examined the two, held them up to the light.
"There isn't much chance of mistaking that 'Zig-Zag' watermark," he said. "This cigarette was made by the deceased; there can't be the shadow of a doubt."
"One more point," said Thorndyke, laying the burnt wooden vesta on the table. "You have his match-box?"
The inspector brought forth the little silver casket, opened it and compared the wooden vestas that it contained with the burnt end. Then he shut the box with a snap.
"You've proved it up to the hilt," said he. "If we could only find the hat, we should have a complete case."
"I'm not sure that we haven't found the hat," said Thorndyke. "You notice that something besides coal has been burned in the grate."
