Malcolm Kershaw, owner of the Old Devils Bookstore in Boston, is approached by FBI agent Gwen Mulvey when a series of murders seemingly copied from a blog of his entitled “Eight Perfect Murders” throws the spotlight his way. Malcolm chose eight of what he considered the best examples of unsolvable murders in literature from authors such as Agatha Christie, Donna Tartt, Patricia Highsmith and John D. MacDonald, and now the killer seems to have used his blog as inspiration. What’s also troubling is that Malcolm knows most of the victims. Is he the killer, writing his narrative in the style of Christie's Doctor Sheppard in The Murder of Roger Ackroyd, or is he potentially a victim? Twists and turns abound in this thrilling new mystery by Peter Swanson.
