Jimmy, catching the last word, gasped involuntarily and Bob nudged him warningly.
“Keep still,” he hissed. “This sure is going to be good!”
The two other men looked uncertain but the fellow called Mohun was pushing the point home.
“This is our chance,” he cried vehemently. “Salper is out of the way for the present, but we never know when he may take the notion to go back to the old job. They say he is getting mighty restive already.”
At the mention of Mr. Salper’s name Bob fell back in his amazement and landed on Joe’s foot, whereupon the latter emitted a squeak of pain that he immediately stifled.
“Did you hear that?” demanded Bob in an excited whisper, without a thought for poor Joe’s foot. “They’re talking about Mr. Salper.”
Eagerly he turned back to the window while Herb whispered in an awed tone:
“Maybe they’re going to murder the old fellow.”
“Say, keep still, can’t you?” said Bob impatiently, as he strained his ears to catch the lowered tones of the three men.
Herb subsided, and the four of them waited with bated breath to find out what these three conspirators had to do with Gilbert Salper.
