Agatha Raisin, retired PR supremo, has been spurned at the altar by the man of her dreams--her attractive neighbor James Lacey. So temporarily deserting the sleepy Cotswold village of Carsely, she pursues her fleeing fianc├(R) to north Cyprus, where, instead of enjoying a romantic honeymoon, they witness the killing of an obnoxious tourist in a disco. Can the duo forget their differences and resume their strangely successful sleuthing partnership?
