Agatha Raisin and Love, Lies and Liquor

Sea, sand - and the slammer for Agatha!
Agatha Raisin thinks she's in for a treat when her ex-husband James Lacey invites her on holiday but - horrors! - his idea of an idyllic break is the small, run-down resort of Burryhill-on-Sea. And from there on things go from bad to worse, so when a fellow guest in their hotel is found murdered, Agatha herself is chief suspect - and has to solve this case from a locked police cell!
