Agatha Raisin
Agatha Raisin and the Day the Floods Came

It can be hell in light water ! Drowned brides are like buses : nothing for ages, then two come along at the same time... Abandoned by husband James, Agatha hops on a plane to the South Pacific, hoping to mend her broken heart. But there she meets a happy honeymooning couple for whom disaster strikes when, tragically, the bride drowns. Back home, alarm bells start ringing for Agatha when a woman, dressed in a wedding gown, is swept down-river.
The police say suicide, but Agatha, spurred on by recent memories, particularly her own disastrous marriage, sets out to prove them wrong.
