Beachaven is a quiet, select sort of coastal resort. Its promenade is small and it has only one fashionable hotel - the Beachaven Hydro. But this peace is shattered when the wealthy businessman, Sir Gilbert Dyall, is found shot in his room, and the Hydro plays host to a baffling murder investigation. Inspector Willard, determined to solve successfully what looks to be one of the final cases of his long career, turns to police surgeon Dr Peter Blayne for help. But when the most promising clue, such as it is, appears to be the bunch of violets found near the corpse, solving the mystery of the Monday night murder will be no easy task...

Originally published in 1935, this is a vintage murder mystery from the golden age of British crime fiction.
