“I was wondering if I could be accommodated here for a few days,” began the historian, blandly. “You see——”

The clerk smiled affably. He also coughed apologetically. His thoughts ran like this: “Oh, no, my fine fellow, you can’t work any slick scheme on us.” Then he said:

“Very sorry, sir, our terms are strictly cash in advance, especially when luggage has been taken away. Of course I don’t doubt that you’re all right,” he added, in a tone which expressed all the doubt in the world.

“Oh!” exclaimed Dave.

“Yes,” said the clerk.

The historian remained thoughtful for a moment.

“Pardon me,” he said, quietly turning away.

“He looks like a pretty good sort,” mused the clerk, glancing at Dave’s retreating form. “Still, you never can tell; usually they’re the slickest kind.”

A few minutes later Dave reappeared.

“When Victor Collins comes in will you kindly give him this?” he said, handing the clerk a sealed envelope.
