Agatha Raisin and the Day the Floods Came: Agatha Raisin, Book 12 (Unabridged‪)‬

Abandoned by new husband James, Agatha Raisin hops on a plane to the South Pacific in the hope that an idyllic holiday will bring some consolation. There, she befriends a honeymooning couple, but tragically, the young bride is accidentally drowned. Returning home to the Cotswolds, Agatha finds herself involved in a strangely similar situation: a woman, dressed in a wedding gown, is found floating in the river. The police say suicide, but Agatha, spurred on by bitter reflections on the married state, sets out to prove them wrong.
