It can be hell in high 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.
