Thompson took the knife, opened the blade, and turned the little toy over and over on his palm.
"Of course," he murmured, "there might be a dozen men wearing things like this on their watch chains——"
"Not here in Clinkerport," interposed Tobias.
"No. That's so. But there is no identifying mark."
"Look at the chain. Drefful fine links, but awful strong."
