Grove of the Caesars

Julius Caesar left his gardens to the citizens of Rome, a peaceful sanctuary across the Tiber. Now the gardens and their sacred grove are dangerous haunts, especially for women alone.

When her husband has to leave Rome, it falls to Albia to supervise his building project in an old grotto. Why has someone buried tattered scrolls by obscure philosophers - and does it involve a worse crime than terrible writing?

Soon that puzzle is overtaken. A woman disappears from her husband's birthday party; she meets a dire fate, then Albia learns that on the same night, two louche slaves given to her family by the brooding Emperor Domitian also vanished in the gardens.

Can Albia remain safe and identify the predator who has made the Grove his killing ground?
