It's been forty years since Paul Rogers spent a night at St. Aidan's Preparatory School. When a biographer asks the now-middle-aged novelist about his youth, it triggers memories that Rogers thought he had lost forever. He begins writing about the summer of 1940, when the Nazis took Paris and his entire boarding school was evacuated to a country house in Devon. There the boys discovered a pastoral countryside whose woods held untold mysteries--one of which, Rogers realizes in hindsight, might have been a murder.

To write about this long-forgotten crime, Rogers digs deep into his past, uncovering terrifying recollections that may or may not be real. Something gruesome happened that summer, but understanding it will force Rogers to clear the fog of memory and unravel its mysteries once and for all.
