Eight Perfect Murders

In 2004, Malcolm Kershaw, the narrator of this outstanding fair-play crime novel from Swanson (Before She Knew Him), began working at Boston’s Old Devils Bookstore, where he posted a list on the store’s blog of eight mysteries in which “the murderer comes closest to realizing that platonic ideal of a perfect murder.” Years later, FBI agent Gwen Mulvey tells him she’s investigating multiple killings that she believes may have been influenced by his blog post. For example, Mulvey is probing the deaths of three people apparently connected only by having a name related to birds, a setup similar to Agatha Christie’s The A.B.C. Murders, one of the books on the list. Mulvey is also looking into a murder that mirrors the circumstances of James M. Cain’s Double Indemnity and hopes that Kershaw can give her a lead as to who might be using his list for a campaign of bloodshed. The stakes rise when Kershaw admits he knew one of the victims but chose not to share that with Mulvey. Swanson will keep most readers guessing until the end. Classic whodunit fans will be in heaven.
