"Oh, and how's that?"

"Do you remember about a week ago, sir, when we wrote off about a new accommodation-ladder for the Puffin? I spelt 'accommodation' with one 'm' and you told me about it. Well, in that forged letter the same word occurred and it had only one 'm.' That was enough to start on. So I telegraphed to you. And then I just kept my eyes open——"

"As a Sea Scout should," added Mr. Grant.

"But I can't much longer, sir," rejoined Peter with another yawn.

CHAPTER V

THE PERIL IN THE FAIRWAY

"This has been a dud cruise, if you like!" observed Patrol-leader Brandon to his particular chum, Craddock. "Mind, I'm not saying that it hasn't been awfully enjoyable, but nothing's happened."

"Do you want anything to happen?" asked Peter. "I don't. I'm quite content to take things as they are in the Puffin."

All the same the weekly cruise had been uneventful. The Puffin had stood well out into the Channel, and after beating to the westward had put into Crabhaven for the night. She was now on her way back to Aberstour, running with spinnaker set and mainsheet slacked right out before a gentle sou'westerly breeze.
