Rome, the very end of December. The Field of Mars is packed with monuments, none more beautiful than Domitian's new Odeon and Stadium. But the area has been overtaken by ugly events: elaborately staged murders. Someone bears a spectacular grudge against the theatrical community, and intends to get revenge in the most spectacular way possible. The killer's method is to re-enact bloody scenes from the gruesome side of popular theatre, where characters in plays really die on stage. A figure from the past wants Flavia Albia's father to investigate, but Falco is out of Rome for the holidays. Albia seizes the commission.
