Whose Body? is a 1923 novel by Dorothy L. Sayers (ISBN 0-380-39966-0), that introduced the character of Lord Peter Wimsey.
It begins with a telephone call to him from his mother, the dowager duchess of Denver, saying that the architect her vicar had hired to do some work on the church has just found a dead body in his bathtub, and it was wearing nothing but eye-glasses. Whose body? is not the only mystery Lord Peter has to solve: Who done it? And why is he naked?
