About this book

In a city where you can invent a past, how do you know whose face to trust?

Arthur Hornblow’s The Mask brings mystery and deception into the drawing rooms of Edwardian New York. This is a city of newcomers, new money and curious eyes, where a person can arrive without a past and build another. Behind the face shown in public lies the question that drives the story: what is being hidden, and why?

A false identity puts more than one reputation under pressure. Friends, lovers and rivals can find themselves caught in a lie they do not understand. Hornblow brings his experience of the theatre to a tale of clear scenes, strong turns and rising tension. The pull comes from watching appearances strain under the weight of secrets.
