Dangerous to know: A compelling story of old loves, old secrets - Barbara Taylor Bradford

Sebastian, the fifty-six-year-old patriarch of the Locke clan, is handsome, charismatic, a man of immense charm and intelligence. He heads up the philanthropic Locke Foundation, funded by the vast family fortune built by his forefathers.

Committed to relieving the suffering of those in genuine need, Locke travels the globe; personally giving away millions a year to the poor, the sick, and the victims of natural disasters and wars. He is seen as a beacon of light in today's darkly violent world. That is why the police are so baffled when Sebastian is found dead in mysterious circumstances. Has he been murdered, and if so, who would want to kill the world's greatest philanthropist? Could such an upstanding man have enemies?

Vivienne Trent, an American journalist, met Locke as a child, divorced him, but stayed close to him. Aware that there was also another side to this enigmatic man, she sets out to find the truth about his death and about Locke himself.
