"Well, first and foremost," continued Dave, "do you recognize that picture, Bob?"
Dave handed out the photograph that Adair had given him on the Swallow.
"Why, sure," answered Bob promptly. "It's a picture of that rascally pilot."
"No, no---I mean the other figure in the photograph."
"Oh--oh!" said Bob slowly, studying it. "N-no," he continued, quite as slowly. "Yes--no. H'm! One minute the face looks familiar, the next it looks strange. I can't fix it, although it seems as if I've seen that man before."
"You have," declared Dave. "Here, Mr. Stoodles, you take a try."
"Yes, there's the pilot," announced Stoodles. "The other is the ould pawnbroker that was on the Raven."
Dave's face grew eager and bright with satisfaction.
"Good for you," he said. "I knew I was right. Yes, that is the man the Hankers picked up at San Francisco--a pawnbroker named Gerstein. He furnished some of the money to fit out their ship for the expedition. Well, my friends, Gerstein, under the false name of Schmitt-Schmitt, is now on this island."
"Then the Raven crowd escaped!" exclaimed Bob.
