ride slower. There seemed no apparent reason why the men should have pulled their car up beside the road, for they were not repairing a breakdown and they were still a little distance from the lane leading to the Morton farmhouse. Then, as the motorcycles slowly passed the car and the three men sullenly regarded the two boys, Frank suppressed an exclamation of surprise.
The three men in the car were the three men who had pursued the boys in the motorboat earlier in the day!
Frank and Joe drove past, conscious of the scrutiny of the unsavory trio in the automobile. The men did not speak, although Frank noticed that one of them drew his cap down over his eyes and muttered something to one of his companions.
When they had gone by, Joe glanced back. The man were paying no further attention to them, but were leaning close together, evidently having resumed their interrupted conversation. There was something stealthy and secretive in their demeanor that was far from reassuring.
"Did you recognize them?" asked Frank, when they were out of earshot.
"I'll say I did! The same gang that followed us in the motorboat."
"I wonder what they're up to."
"Up to no good, by the looks of them."
