A mysterious widow pursues Flavia's father and a lion terrorizes the streets of Ostia in the sixth "Roman Mysteries" adventure.

December, A.D. 79. It is the month of the Saturnalia, a festival when people do as they please, and anything can happen. When a Roman widow, Cartilia Poplica, shows unusual interest in Flavia's father, Captain Geminus, Flavia decides she must find out what Cartila's motives really are. To do so, she finds she must perform twelve tasks, just like the Greek hero Hercules. And what is more, there's a lion loose in the streets of Ostia.
