Harold Wilson, police sergeant in the picturesque Cotswolds village of Bunburry, loathes Alfie McAlister. Alfie is handsome, popular, a self-made multimillionaire - and worst of all, he and his friends Liz and Marge are much better than the police at catching villains. But Sergeant Wilson loathes one person even more - Bunburry's vicar, Philip Brown - and is thrilled by the chance of locking him up for a local crime. When Reverend Brown refuses to defend himself or produce an alibi, it's up to the Bunburry Triangle to uncover what's going on.
