"That villain has caused us more trouble than any other criminal we ever attempted to run down. I'll even matters up with him. Had you not retreated just when you did, that knife would surely have killed you."
"I'll be laid up a few days, the doctor said," replied Harry, "but I'll soon get over it. If I ever meet La Croix again, I won't have any mercy on him. He's a bad man."
The boy then went to bed.
A week afterward, Old King Brady met Harry at police headquarters, and the boy saw by the look of triumph on his face that he had good news.
"How are you feeling to-day?" he asked the boy.
"Fine. My wound don't bother me at all."
"I've been working hard, Harry."
"So I imagine, as I haven't seen anything of you since yesterday."
"La Croix's four spies have arrived in town."
"What! Come from Canada?"
