The Silver Pigs is a 1989 historical mystery crime novel by Lindsey Davis and the first book in the Marcus Didius Falco Mysteries series. Set in Rome and Britannia during AD 70, just after the year of the four emperors, the novel stars Marcus Didius Falco, informer and imperial agent. The book's title refers to 200-pound lead ingots "pigs" filled with silver ore and stolen from Roman Britain, which feature prominently in the plot. Plot summary This first novel in the Marcus Didius Falco Mysteries series introduces the main characters as well as establishes relationships that continue and grow throughout the series. Falco stumbles upon a conspiracy in the trading of silver ingots, but not before it claims the life of a young girl (Sosia Camillina) Falco meets and is smitten with. Hired by Sosia's uncle, a senator, to find out who murdered her and by the Roman Emperor Vespasian, to uncover the conspiracy, Falco finds himself on the next boat to Britain. Once there he meets a lady way out of his class, Helena Justina, the daughter of the Senator who hired him, and Sosia's cousin. At first sight Falco and Helena loathe each other: He hates her class, and she hates his prejudice. Things are made no easier by Sosia's death, especially for Helena. Working under cover, Falco himself working down a silver mine, acting as a mine slave, Falco learns the meaning of hate, pain and abuse. After being rescued by Helena and a friendly centurion, Falco heads back to Rome, as the reluctant charge of the even more reluctant Helena. After spending so much time together, and many arguments, misunderstandings and denials, Falco and Helena fall in love (and subsequently consummate this in a horse stable, in a public garden). Eventually, Falco sorts out the case and only has to bring the culprits to justice. However, there is no justice, as one of the culprits is Domitian, the Emperor's wayward son, and the only other surviving culprit is very close to Helena and her senator father. After a final, bloody, retribution is carried out in the climax, Falco is offered a promotion to the equestrian rank. As an equestrian Falco would be upper middle class and could marry Helena without bringing her or her family shame, as would with his current meagre earnings. He refuses, seeing the offer as a bribe to keep the conspiracy hushed-up.
