As soon as they passed the corner of the untenanted hotel they obtained an open view over the smooth water of the bay. Outside the breakwater lay a large pleasure yacht, painted white, with steam up.

"What sort of a boat is that?" asked Wallion sharply.

"Go in there and don't stick even the tip of your nose out of the door."
