Asylum by Patrick McGrath

In the summer of 1959 Stella Raphael joins her psychiatrist husband, Max, at his new posting–a maximum-security hospital for the criminally insane. Beautiful and headstrong, Stella soon falls under the spell of Edgar Stark, a brilliant and magnetic sculptor who has been confined to the hospital for murdering his wife in a psychotic rage.

But Stella’s knowledge of Edgar’s crime is no hindrance to the volcanic attraction that ensues–a passion that will consume Stella’s sanity and destroy her and the lives of those around her.
