Close behind him was a policeman slowly pacing his regular round. Herbert went up to him, and, pointing to Greenleaf, rapidly recounted his grievances.
“It was a mean trick,” said the policeman, who was a favorable specimen of his class. “Is this the first time you have seen him?”
“Yes.”
“Tell me what you want to do.”
“I want to get my money back.”
“Probably he has spent it. How long since he robbed you?”
“Three weeks.”
“Not much chance, then. Probably his pocket's empty, unless he's fleeced somebody else in the meantime. However, it's as well to see what can be done. Now, I'll tell you how to act. Go up to him boldly, and demand your money. If he bluffs you off, call me.”
“All right,” said Herbert.
He hastened his step, and, advancing, tapped Greenleaf on the shoulder.
