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 and faced extreme peril with her best friend Hector over Christmas, Aggie's Morbid Preoccupation is on alert when rumours abound about the spa's recently deceased former patient…and then another body appears under mysterious circumstances.

Together with Grannie Jane, and often in the company of George, a young patient at the spa, Aggie and Hector take a closer look at the guests and staff of the Wellspring Hotel, and venture into the intriguing world of the local undertaker. Has there been a murder — or even two? As Aggie and Hector ignite their deductive skills, their restful trip takes a sudden, dangerous turn. (From Tundra Books)
