Because Gussie is locked up in prison he cannot show up at Deverill Hall, which might induce Madeline Bassett to renew her efforts to ensnare Bertie. After explaining the why of this to Corky and Catsmeat Bertie turns to Jeeves for advice, who suggests that somebody else should impersonate Gussie at the Hall. Catsmeat declines, and the buck stops at Bertie, who reluctantly accepts to play the part., also agreeing to take Sam the dog with him because Corky's uncle is not too keen on dogs and Corky wants him to be introduced at a later stage.
