London: 1968. Liz Houghton is languishing as an obituary writer at a London newspaper when a young girl's disappearance captivates the city. If Liz can break the story, it's her way into the newsroom. She already has a scoop: her best friend, Marisa, is a police officer assigned to the case.

Liz follows Marisa to Dorset, where they make another disturbing discovery. Over two decades earlier, three girls disappeared while evacuating from London. One was found murdered in the woods near a train line. The other two were never seen again.

As Liz digs deeper, she finds herself drawn to the village of Tydeham, which was requisitioned by the military during the war and left in ruins. After all these years, what could possibly link the missing girls to this abandoned village? And why does a place Liz has never seen before seem so strangely familiar?
