When Ruth lets her neighbour and sidekick Doris accompany her on a trip to Cape Bridgewater, an idyllic coastal location known for its pristine natural beauty, the last thing she expects to find is a body.

With a feature to write and the promise of romance in the air, Ruth is reluctant to investigate another mysterious death. But Doris has other ideas, and drags Ruth into the confusing world of a local family's inheritance dispute over a rundown old farm.

With few clues and many culprits, their investigations seem to be going nowhere - until a shocking discovery turns the whole case on its head.

Set in southern Australia, A CAPE, A ROCK AND A MURDER is the third book in Isobel Blackthorn's series of cozy mysteries.
