“She’s waiting for us to go on!” Penny guessed shrewdly. “For some reason, she doesn’t want anyone to know where she’s going!”
“Then let’s wait and watch!”
“We’ll learn nothing that way. She can tell we’re keeping our eye on her.” Penny threw in the clutch and the car rolled away from the curb. “Tell you what, Lou! We’ll drive around the block.”
“Good idea!” approved her chum. “That way she’ll think we’ve gone and we can see where she really goes.”
Penny turned at the first corner and made a quick trip around the block. As they again came within view of the ice-locked river, the girls looked quickly up and down the street for a glimpse of their former passenger.
“There she is!” Louise cried. “Why, she’s walking straight to the docks!”
The two girls now were completely mystified and not a little worried. At this late hour, the waterfront was deserted.
Penny watched the retreating figure for a moment, and then swung the car door open.
“That girl can’t know what she’s doing!” she decided. “I’m going after her!”
“For our pains, we may be told to mind our own affairs.”
