Former PR supremo turned amateur sleuth Agatha Raisin thinks she's in for a treat when her ex-husband James Lacey actually invites her to go on holiday with him. But, horror! His idea of an idyllic break is the small, run down resort of Snoth on Sea. And once they arrive at this less than exotic spot, things naturally start to go from bad to worse. W fellow guest in their hotel is found murdered, and soon poor Agatha herself becomes a suspect ... she must solve this particular case from her prison cell!
