“Last week you could buy a rat for six francs, but,” and here he swore vilely, “the rats have quit the Rue de Seine and they kill them now over by the new hospital. I’ll let you have this for seven francs; I can sell it for ten in the Isle St. Louis.”

“You lie,” said Trent, “and let me tell you that if you try to swindle anybody in this quarter the people will make short work of you and your rats.”

He stood a moment eyeing the gamin, who pretended to snivel. Then he tossed him a franc, laughing. The child caught it, and thrusting it into his mouth wheeled about to the sewer-hole. For a second he crouched, motionless, alert, his eyes on the bars of the drain, then leaping forward he hurled a stone into the gutter, and Trent left him to finish a fierce grey rat that writhed squealing at the mouth of the sewer.
