"It is platinum. An expensive chain. Not likely, after all, to be worn by many."
"That kind of narrows suspicion down, doesn't it?" said Tobias with some eagerness.
"It must. A platinum watch chain costs a deal of money, Tobias. There must be an excellent watch at the other end of the chain. No ordinary person would be likely to wear such an ornament. These burglars——"
"Maybe they stole it," suggested Tobias.
Thompson looked at the red book again. He wagged his bushy head, and sat, tight-lipped and thoughtful.
"That is possible," he finally agreed. "But if the knife and the few links of chain can be traced——"
"'Tis a clue," Tobias said. "Looks like somebody might be in this job who wasn't just an ordinary burglar. Heh?"
"I'll allow that, Tobias."
"Well, that is all I had to tell you, Mr. Thompson. I reckon you'll give the knife to the city detectives when they come?"
"Naturally. I will put all possible clues into their hands," the bank president rejoined, glancing again at the little red book.
