Toby O'Dare, former government assassin, is summoned by the angel Malchiah to fifteenth-century Rome-the city of Michelangelo and Raphael, of Leo X and the Holy Inquisition-to solve a terrible crime of poisoning and to uncover the secrets of an earthbound restless spirit, a diabolical dybbuk. Toby is plunged into this rich age as a lutist sent to charm and calm this troublesome spirit. In the fullness of the high Italian Renaissance, Toby soon discovers himself in the midst of dark plots and counterplots, surrounded by a still darker and more dangerous threat as the veil of ecclesiastical terror closes in around him. And as he once again embarks on a powerful journey of atonement, he is reconnected with his own past, with matters light and dark, fierce and tender, with the promise of salvation and with a deeper and richer vision of love.
