Some holidays are to die for... others are just deadly.

A scenic tour of Cornwall's dramatic coastline should be the perfect getaway for the awesome foursome - and it is - until the tour's history expert takes a fatal plunge from Tintagel Castle.

Lady Marjorie Snellthorpe has seen enough suspicious deaths to know an accident when it isn't one. While the local police write off the victim's demise as a tragic mishap, Marjorie and her three unlikely companions - sharp-tongued Edna, charming Horace and methodical Frederick - start digging deeper.

What they uncover is a web of bitter vendettas among their fellow travellers. The victim had a talent for making enemies - from his vengeful ex-wife to students nursing old wounds. When a second member of their group barely survives a drowning attempt, the message is clear: the killer isn't done.

Armed with savvy instincts, endless curiosity and a healthy supply of tea, can Marjorie and her friends solve the case before their Cornish adventure becomes their final cliff-hanger?

A delightfully British cozy mystery filled with friendship, wit and just enough red herrings to keep you guessing until the very last page. Fans of Richard Osman's The Thursday Murder Club will adore this.
