　　Barnaby accompanies Joyce on a spa weekend to Swavely Manor. But as he attempts to de-stress, a woman is found dead in the floatation chamber. Abandoning the treatments to investigate, Barnaby uncovers a feud between neighbours, money wrangles and the mystery of a half-written novel. Then there's another death. But his personal worries are never far from the surface.
