Brat Farrar

In Brat Farrar, Josephine Tey presents one of the most attractive imposters in mystery fiction. Young Farrar, a product of an orphange, closely resembles the dead heir-presumably sucicide-to Lachetts, a British country estate. Mostly because of his great love of horses he is persuaded to pose as Patrick Ashby, the heir, and claim the inheritance. When an attempt is made on his life, Farrar knows Patrick was murdered and by whom-but to reveal it he would have to reveal his own fraud.
