Written in Stone, the tenth installment in the Scottish Bookshop series by Paige Shelton, set in a specialty bookstore in Edinburgh called The Cracked Spine. When Delaney wins a special Hidden Door Festival invitation to artist Ryory Bennigan's studio, she isn’t sure quite what to expect. What she finds is an elusive fellow obsessed with the Picts—complete with his own versions of their blue tattoos and vibrant red hair—recreating the stones they left behind. She also meets a visiting paleontologist, Dr. Adam Pace, from the University of Kansas attempting to sell an artifact that might just explain what the Picts' language really sounded like. Or at least that’s what he claimed the artifact was for. Before the deal can close and Ryory can get a closer look at it, Dr. Pace is found dead. With the police dragging their feet in the investigation, Delaney takes it upon herself to dig into Dr. Pace's past. Her research goes murky as she quickly discovers Pace’s shady background—selling fake dinosaur bones and running into some 3D-printing trouble back in Kansas. Could his past have come back to bite him in Edinburgh? And what does his questionable background mean for the mysterious Pictish artifact he was trying to sell to Ryory? Delaney will have to dust off her magnifying glass to uncover the truth behind this case... or risk becoming a pile of bones herself.
