The Tell-Tale Corpse by Harold Schechter

In this mystery Edgar Allen Poe goes to Boston and Concord to try to cure his wife's debilitating illness. He finds himself a guest of the Alcott family, a particular friend of young Louisa May Alcott, and called upon to solve a series of brutal murders. I found the chase fun, although the prose is a little stilted (I find the author's attempt to sound like a nineteenth century author or Poe himself false).
