Showing A Dying Light in Corduba by Lindsey Davis

One of the stories from the bestselling historical fiction Falco series. Nobody was poisoned at the dinner for the Society of Oliver Oil Producers of Baetica, though in retrospect this was quite a surprise...

Inimitable sleuth Marcus Didius Falco is back with a vengeance. On one night, a man is killed and Rome's Chief of Spies left for dead. This leaves no one except Falco to conduct the investigation. Soon he is plunged into the fiercely competitive world of olive oil production. Political intrigue, an exotic Spanish dancer and impending fatherhood all add to Falco's troubles.
