The other boat was now almost upon their craft. It nosed out to the right and drew alongside, coming dangerously close. The boys could see the three men clearly and they noticed that all three scrutinized them, seeming to pay particular attention to Chet and Biff.
The men were unsavory looking fellows, unshaven, surly of expression. The man at the helm was sharp-featured and keen-eyed, while the other two were of heavier build. One of the pair wore a cap, while the other man was bare-headed, revealing a scant thatch of carroty hair so close-cropped that it seemed to stick out at all angles to his cranium. This man, the boys saw, nudged his companion and pointed to Biff, who was too busy at the helm of his own craft to notice.
"Not so close!" yelled Chet, seeing that the other boat was running broadside in dangerous proximity to the Envoy.
In reply, the man at the helm of the other craft merely sneered and brought his boat in until the two speeding launches were almost touching sides.
"What's the idea?" Joe shouted. "Trying to run us down?"
