Not a sail was in view below.

Frank was discouraged.

He thought they would overtake the May Queen.

“You ought not feel down-hearted over it,” said the detective, consolingly, although he felt disgusted himself. “She may have changed her course so that we might have passed her.”

“Suppose we head for Liverpool. We can find out all about her there and wait for her to come in.”

“That’s a very sensible plan.”

A rattling sound overhead reached Frank’s car at this moment, and he glanced up at the big stern helix.

A bolt at the top of the post had worked itself loose.

In a few moments it might fly off and injure the wheel.

He hastened below, procured a long-handled wrench and went up the frame to tighten the bolt.
