When Sandro Cellini agrees to become head of security for a luxurious private residence overlooking the glittering expanse of Florence, he has no idea of the horrors he is about to uncover.

When private investigator Sandro Cellini is invited to attend a glamorous launch party for a luxury residence overlooking Florence, he has no idea what he's walking into. Behind the austere beauty of Palazzo San Giorgio's façade terrible secrets lie hidden: not only an old torture chamber uncovered during excavations, but a much more recent malevolence.

Then the head of security dies under suspicious circumstances and Sandro takes on the dead man's role. He soon discovers that his predecessor's death was not random, or isolated, when one of the residents is found murdered in her room. Now, Sandro must work to untangle the secrets of the palazzo to unmask a deadly killer before the fate of another victim is sealed.
