It's an eventful day at Sunset Hall, a house-share for the old and unruly, when the police arrive with news that a body has been discovered next door. Everyone, including Agnes, is secretly relieved that the body in question is not the one they're currently hiding in the shed (sorry about that, Lillith). Now the answer to their little problem with Lillith may have fallen into their laps. All they have to do is find out who murdered their neighbour, so they can pin Lillith's death on them, thus killing two old birds with one stone. To investigate, the senior sleuths (not forgetting Hettie the tortoise) will tangle with sinister bakers, broken stair lifts, inept criminals and their own dark secrets.
