International Bestseller Winner of the Edgar Award for Best Novel "This lively whodunit keeps you guessing until the end." --People "Utterly bewitching...As unforgettable as it is original." --A.J. Finn "Goose-bump spooky, smart, and haunting...I loved this book!" --Louise Penny Death lies between the lines when the events of a dark story start coming true in this haunting modern gothic mystery, perfect for fans of Magpie Murders and The Lake House. Clare Cassidy is no stranger to murder. A high school English teacher specializing in the Gothic writer R. M. Holland, she teaches a course on it every year. But when one of Clare's colleagues and closest friends is found dead, with a line from R. M. Holland's most famous story, "The Stranger," left by her body, Clare is horrified to see her life collide with the very gothic literature she teaches. To make matters worse, the police procedural that follows suggests the killer is someone Clare knows. Unsure whom to trust, she turns to her closest confidant, her diary, the only outlet she has for her darkest suspicions and fears about the case. Then one day she notices something odd. Writing that isn't hers, left on the page of an old diary: Hallo Clare. You don't know me. Clare becomes more certain than ever: "The Stranger" has come to terrifying life. But can the ending be rewritten in time?
