"I'm quite happy as I am, and it's rather hot to go sight-seeing, isn't it?" Her voice sounded weary.

Chris looked at her sharply.

"You're not feeling so well as you'd like me to believe," he said suspiciously.

Marie frowned.

"If only you wouldn't persist in making me an invalid," she complained.

Chris was offended.

"Oh, very well! It was only for your own good." His face changed a little. "Here comes Feathers," he added.

He had not seen his friend that morning, and he was not sure what sort of a reception he was going to receive, but Feathers behaved as if nothing had happened. He remarked that it was a lovely 86 morning and that the sea was warmer than it had been for a month.

"Have you been in?" Chris asked eagerly.

"Yes—just come out."
