Aspiring writer Aggie Morton is ready to enjoy an invigorating trip to a Yorkshire spa, where her widowed mother can take the waters and recover from a long mourning period. Having solved yet another murder - not to mention rescuing her best friend Hector from certain death - over Christmas, Aggie is looking forward to more splendid adventures with Hector, who has joined Aggie, her mother and Grannie Jane on this trip. There is even a potential new friend in George, a young patient at the spa. But rumors abound about the spa's recently deceased former patient, and then another body appears under mysterious circumstances. Has there been a murder - or even two murders? Aggie's Morbid Preoccupation kicks in and once again she and Hector will have to put their deductive skills and imaginations to work, as their restful trip takes a sudden, dangerous turn.
