Busman's Honeymoon: Lord Peter Wimsey Book 13 by Dorothy L Sayers
They plan to have a quiet country honeymoon. Then Lord Peter Wimsey and his bride Harriet Vane find the previous owner's body in the cellar. Set in a country village seething with secrets and snobbery, this is Dorothy L. Sayers' last full-length detective novel. Variously described as a love story with detective interruptions and a detective story with romantic interruptions, it lives up to both descriptions with style.'I admire her novels ... she has great fertility of invention, ingenuity and a wonderful eye for detail' P. D. James
