Agatha Raisin and the Day the Floods Came. by M.C.Beaton.
Just as Agatha returns home from a South Pacific holiday her village is hit by severe floods. As the local river is forced under and around the village bridge a body is seen floating amid the waves. This is a similar situation that Agatha faced on her holiday as no sooner had she befriended a honeymoon couple than the young bride accidentally drowned. Here in her own village the body in the river is not only a young woman but one dressed in a wedding gown.
Consequently Agatha's interest(although the local police call it interference) in the mysterious 'river' body is not quenched till the murderer is found. Along the way she wears many disguises and is aided by her new neighbour , a crime author, who just happens to be handsome , smart and apparently single. Could he be the new man in her life...
An excellent book, crime, murder, drugs -- they were all used to develop the story. I find Agatha Raisin such a likeable character and the books are always a joy to read.
