“Swanson rips us from one startling plot twist to the next… A true tour de force.” —Lisa Gardner

"Fiendish good fun." —Anthony Horowitz

From the hugely talented author of Before She Knew Him comes a chilling tale of psychological suspense and an homage to the thriller genre tailor-made for fans: the story of a bookseller who finds himself at the center of an FBI investigation because a very clever killer has started using his list of fiction’s most ingenious murders.Years ago, bookseller and mystery aficionado Malcolm Kershaw compiled a list of the genre’s most unsolvable murders, those that are almost impossible to crack—which he titled “Eight Perfect Murders”—chosen from among the best of the best including Agatha Christie’s A. B. C. Murders, Patricia Highsmith’s Strangers on a Train, Ira Levin’s Death Trap, A. A. Milne's Red House Mystery, Anthony Berkeley Cox's Malice Aforethought, James M. Cain's Double Indemnity, John D. Macdonald's The Drowner, and Donna Tartt's A Secret History.

But no one is more surprised than Mal, now the owner of the Old Devils Bookstore in Boston, when an FBI agent comes knocking on his door one snowy day in February. She’s looking for information about a series of unsolved murders that look eerily similar to the killings on Mal’s old list. And the FBI agent isn’t the only one interested in this bookseller who spends almost every night at home reading. There is killer is out there, watching his every move—a diabolical threat who knows way too much about Mal’s personal history, especially the secrets he’s never told anyone, even his recently deceased wife.

To protect himself, Mal begins looking into possible suspects . . . and sees a killer in everyone around him. But Mal doesn’t count on the investigation leaving a trail of death in its wake. Suddenly, a series of shocking twists leaves more victims dead—and the noose around Mal’s neck grows so tight he might never escape.

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.
