The plot of Sir Henry at Rawlinson End revolves around attempts to exorcise the ghost of Humbert, the brother of drunken aristocrat Sir Henry Trevor Howard. Humbert was accidentally killed in a drunken duckshooting incident whilst escaping trouserless from an illicit tryst. It transpires that Humberts ghost will not rest until it is supplied with replacement trousers. Until then the ghost walks the corridors of Rawlinson End, often accompanied by that of Humberts dog Gums which has repossessed its own body, now stuffed and mounted on a trolley. Amongst the eccentric family members, mad friends and grudgingly loyal servants involved are the eternally knitting Aunt Florrie, the tapewormobsessed Mrs. E, Lady Philippa of Staines Liz Smith, who enjoys the oddsmall sherry and the everpresent Old Scrotum, Sir Henrys wrinkled retainer.
