But the week was over at last and on Saturday morning Fenton Hardy looked up from his newspaper with a quiet smile.

"What's the program for to-day?" he asked of his sons.

"Nothing in particular," said Frank. "I was thinking I'd dig into the Latin for an hour or so, although I'm so sick of the sight of that book that I'd like to throw it out the window."

"I'm away behind in my algebra," spoke up Joe. "But it's too nice a day to study. Anyway, I've been working hard all week."

"Perhaps if you went down to the boathouse you might find something there," suggested their father casually.

The boys stared incredulously. Then they gave a simultaneous whoop of delight.

"You don't mean to say the motorboat is here?" exclaimed Frank.

Their father had taken charge of the buying of the motorboat for them. They had not expected that the craft would arrive until the start of the summer holidays.

Fenton Hardy merely smiled and turned to the financial page.

"It mightn't be a bad idea to go down to the boathouse anyway," he said.
