Jane Marple is being treated to a few days' holiday by her niece, staying at Bertram's Hotel - a dignified, establishment tucked away in a back street of busy Mayfair. It is a place where sedate upper-class ladies, retired military gentlemen and the higher echelons of the clergy can indulge in the comforts of a bygone age. But Miss Marple begins to feel uneasy. Something sinister lurks beneath the polished veneer. Why are so many major crimes associated in some way with the hotel and those eminently respectable people staying there? Instead of rest and relaxation, Miss Marple finds herself hard at work as she attempts to discover what goes on behind closed doors. Siân Phillips and Maurice Denham are among the cast of this absorbing mystery, starring June Whitfield as Miss Marple.
