In order to recuperate from her last escapade and re-grow some hair, Agatha Raisin goes on holiday to the seaside town of Wyckhadden. However, the holiday is not what Agatha hoped for. The weather is crummy, all five of her fellow hotel guests are elderly, and time hangs heavy. A chance discussion with a fellow guest leads her to the door of Francie Juddle, a local woman who claims to have the power of witchcraft. Agatha is not impressed with Francie, but does buy a hair potion and a love potion.
