At once a psychological thriller and a social critique, Seven Types of Ambiguity is a novel of obsessive love in an age of obsessive materialism.

Following years of unrequited love, an out-of-work schoolteacher decides to take matters into his own hands, triggering a chain of events no one could have anticipated.

This is a story of impulse and paralysis, of empty marriages, lovers and a small boy, gambling and the market, of adult children and their parents, of poetry and prostitution, psychiatry and the law.

Published to huge acclaim in the author's native Australia, Seven Types of Ambiguity was hailed as 'a tour de force' (The Age) and described as 'Perlman's achingly humane, richly layered and seamlessly constructed masterpiece' (Canberra Times).
