The Mystery of the Invisible Thief

Buster, don’t pant so violently—you’re making me feel even hotter!”Buster crawled into a patch of shade, and lay down with a thump. His tongue hung out as he panted. Bets patted him.“Poor old Buster! It must be frightful to have to wear a fur coat this weather—one you can’t even unbutton and have hanging open!”“Don’t suggest such a thing to Buster,” said Fatty. “He’d look awful.”“Oh dear—it’s too hot even to laugh,” said Daisy, picturing Buster trying to undo his coat to leave it open.
