Passion (Unabridged‪)‬

Orphan William Hyde and professor's daughter Melissa Elmet fell passionately in love as teenagers at Oxford. But, after her family intervenes, their secret marriage is annulled. Heartbroken, Melissa retreats into her shell, now a shy academic. Will, on the other hand, joins MI6 - then becomes a millionaire in New York, with a model girlfriend and only dark memories of the young woman who broke his heart.

Their lives are completely different. They'll never meet again. And then the killings start. Only Will notices the link to all four high-profile murders: Melissa's late father, the secretive professor who died working on a confidential project. And now he fears the next hit will be Melissa - unless he can get to her first.
