A decade ago, when he started working at Old Devils bookstore in Boston, Malcolm Kershaw published a blog post listing the most unsolvable murders appearing in classic mystery novels.  No one read it.  At least that's what Malcolm thought.  Now, ten years later, a string of murders has been committed and FBI agent Gwen Mulvey thinks the killer is using his list as a guide map.  

When Gwen asks for Malcolm's help, he hesitates.  Truth is, he knew one of the victims.  If he tells Gwen, suspicion might land on him, which is the last thing he wants considering all the secrets he's keeping ...

I don't want to say too much about the plot of Eight Perfect Murders by Peter Swanson.  The less you know going into it, the better.  Despite its appearances, the novel features a slow-burn kind of story that becomes more engrossing as it goes.  Malcolm is not a super likable character, although he is a sympathetic one.  I related to his love of books and mysteries, even though his constant references to genre classics made me feel woefully under-read!  While I had my suspicions about certain members of the story's cast, Eight Perfect Murders did keep me guessing, which kept me reading even though it's not exactly an edge-of-your-seat thriller.  While I didn't love this book, I did appreciate its original premise, its twists and turns, and the fact that I was still thinking about the story days after I finished it.
