Vengeance

It's a fine day for a sail, and Victor Delahaye, one of Ireland's most successful businessmen, takes his boat far out to sea - then kills himself in front of his partner's son. This mysterious death immediately engages the attention of Detective Inspector Hackett and his sometime partner, Quirke, consultant pathologist. The stakes are high, and Hackett and Quirke must proceed with caution as they question Mona Delahaye, the dead man's young and very beautiful wife; James and Jonas Delahaye, his identical twin sons; and Jack Clancy, his ambitious, womanizing partner. When a second - and even more shocking - death occurs, it becomes clear that a terrible secret threatens to destroy the lives and reputations of Dublin's elite.
