The Traitors' Gate (Richard Jackson Books (Atheneum Paperback))

It’s 1849, the year John Huffman’s father is sentenced to London’s Whitecross Street Prison. He’s been put away for gambling debt—leaving fourteen-year-old John and his family out on the street. But it seems gambling is the least of their problems: Father Huffman is accused of treason. Surrounded by a cast of sinister and suspicious characters, John’s not sure what to believe…or whom.
