Legacy by Murray Smith

Sir Jack Fitzrowan, fourteenth baroner and electronics millionaire, died sailing off the Nantucket Sound. With his will comes a shocking legacy which leaves the bulk of his fortune, $300,000,000, to someone his family never knew existed --- a secret love child, illegaly sold at birth by a corrupt Donegal priest.

Is the boy still alive? Is the maverick millionaire's true legacy one of heartbreak or revenge? Was his death really an accident? Detective Lieutenant Tom Hanrahan of the Boston Police Department begins to doubt it.
