Samuel is Macky's father, a successful silversmith. A warm, friendly and wise man, he was born Jewish, but later joined the Friends of Jesus.

Because of the war they're fighting in Jerusalem, the Romans are suspicious of nearly all the religious groups within their Empire. So Samuel and the Friends of Jesus must exist in secret. When the Romans decide to try and break up the Friends of Jesus, Samuel is forced to make a difficult decision: should he sit back and enjoy the profits of his successful small business, or should he risk everything by working with the rebels, and helping the Friends?
