Old King Brady drew the paper from his pocket and glanced at it keenly.
Once more he was surprised to discover that it was a genuine printed form stating that Mr. Gloom was permitted to remove the corpse of Albert Reid from the Thirty-sixth street house to the Fresh Pond Crematory. The permit added that the broker had died of small-pox.
"We can't say he lied about this, either," commented the old detective.
"But how about the gory dagger you said you found in the empty house?"
"Here it is. And it's a very unique weapon."
Old King Brady held up the knife.
It had a double-edged blade, eight inches long, as thin as paper, and was embossed with the initials P. V., in frosted letters.
"What an ugly-looking weapon!" Harry commented, with a shudder.
"It's an oddity," replied the old detective. "But it isn't a certainty that these are the initials of the person who last used it."
"You'd better keep those three things," advised Harry, thoughtfully. "They may come in handy if this case amounts to anything."
