“You may be right, Draper. Watch the whelp. I’ll fix him.”

“I’ll watch him, all right,” returned Draper, with a warning scowl.

“Gee! I’m in wrong now, for fair,” thought Patsy, thoroughly disgusted with the turn of the situation. “Fix me, eh? I wonder what’s coming. The infernal rascal has something up his sleeve. Infernal rascal is right, too, and I wish I had phoned the chief before butting in here.”
