Welcome to a thrilling new series, "Crime & Passion," from USA Today Bestselling Author Mary Lancaster. London, 1851 In the shadow of the Great Exhibition, poverty and crime stalk the meaner backstreets of the city. But sin is not confined to the underworld. One couple passes seamlessly between the neighboring worlds of privilege and privation, solving crimes and enabling love to bloom. An unforgettable night at the opera... When she accompanies her family to Covent Garden, Lady Grizelda Niven does not expect to be discovered in a nearby back street, clutching a dagger over the dead body of her maid. However, she is even more surprised when the police arrest, not her, but, the devastatingly handsome young man who found her. Clearly, it behooves her to have him released and to enlist his alliance in discovering who truly killed Nancy. Dragan Tizsa, a Hungarian refugee doctor, revolutionary, and soldier, lives constantly with the anguish of loss. The death of one more acquaintance makes little difference to him, except that it brings the vital and eccentric Griz into his life. He is a man who likes puzzles, and the mystery that is Griz soon assumes as much importance as that of the murder. As they work together to unravel the layers of Nancy’s life and discover why she died, friendship and attraction blossom, much to her family’s unease. From the danger of London’s underworld, to the glittering salons of her married sister, Griz and Dragan look out for each other. But is she right to believe in her new friend when the evidence begins to tell against him? And as she comes face to face with the killer at last, is love and happiness forever beyond her reach?
