From the author of the bestselling The Essex Serpent comes a darkly inventive and deeply moving novel that speaks urgently to our times.
Oh friend, take my hand - I've been so lonely!
One winter night in Prague, Helen Franklin encounters her friend Karel, half-mad with fear.
He has come into possession of a mysterious old manuscript, filled with testimonies that speak to Helen from 17th-century England, wartime Czechoslovakia, the sweat-soaked streets of Manila and 1920's Turkey. All of them tell of being followed by a tall, silent woman in black, bearing a terrible message.
Helen reads its contents with intrigue, but everything in her life is about to change.
