The Understudy by David Nicholls

A chronically out-of-luck actor ekes out a living as the understudy to a swaggering West End star, shuffling between humiliating gigs and a crummy bedsit while nursing a bruising mix of envy and hope. When he befriends the star’s disillusioned wife and edges toward betrayal, a chain of comic calamities forces him to choose between scheming his way into fame and salvaging his self-respect. A brief, chaotic taste of the spotlight ultimately nudges him toward a humbler kind of success, where authenticity and small loyalties matter more than applause.
