An elderly sex-pest is at large in DI Purbright’s home town. Leaping out from behind bushes at unsuspecting females, making lewd suggestions and, when challenged, scuttling away with odd off-balance leaps, he soon earns the nickname of the ‘Flaxborough crab’. No one can identify him, and it turns out that quite a few older gentlemen have begun exhibiting over-familiar behavior around the opposite sex. Suave Dr Meadow knows more than he is letting on, yet how can Purbright , aided once again by the fragrant but dodgy Miss Lucy Teatime, get him to talk? Events take a darker turn before the ill-assorted pair succeed in catching their crab.
