Uncle Dynamite
Uncle Fred has just arrived at Ashenden Manor, home of Sir Aylmer Bostock, Pongo's future father-in-law. Pongo is already in residence and has committed two rank floaters: accidentally smashing a whatnot from Sir Aylmer's collection of African curios, and (in the course of demonstrating how Brazilian natives kill birds with rude slings) smashing a coveted bust of his host.
Pongo's solution is to replace the busted bust with another one, abstracted from Ickenham hall. But unknown to him, the replacement bust was fashioned by his former fianc�e Sally Painter, and conceals valuable jewellery that a friend of hers was planning to smuggle through New York Customs.
Sally tries to replace the bust with another of Sir Aylmer she sculpted (but had had returned to her, after an unfortunate incident relating to her brother Otis' publication of Sir Aylmer's memoirs), but this comes to naught, and both busts end up in Sir Aylmer's collection room.
Uncle Fred sees these not as reverses, but opportunities to show his stuff. Having met Bill Oakshott (the nominal owner of Ashenden Manor, but under the thumb of his uncle Sir Aylmer) on the train, he contrives to get invited to the house�under the name of Major Brabazon-Plank. Unfortunately, the local Constable, Harold Potter, happens to have grown up with Major Plank (and also happens to remember arresting Uncle Fred and Pongo at the dog races under the names of Edwin Smith of Nasturtium Road, East Dulwich). Potter, intimately tied to the household through his fianc�e, the housemaid Elsie Bean, becomes suspicious, and watches the house.
Uncle Fred's tasks before him are to snatch the bust for Sally Painter; get Sir Aylmer to drop his suit against Otis, so Sally will not lose the money she invested in his firm; convince Pongo to turn down Hermione Bostock and marry Sally instead;,,,,
