The Sally Lockhart Mysteries Collection

Sally Lockhart (Billie Piper) attempts to find the meaning behind her late father's last letter which contained the phrase "the seven blessings" - a cryptic message that can strike a man dead with fear. Sally is helped by her friends, including Frederick Garland (J.J. Feild), a photographer, and Jim (Matt Smith), a young assistant at the family's shipping firm. The ever twisting mystery involves assassins, opium dens, Chinese gangs, and the Ruby of Agrapur. The priceless ruby is also sought by the ruthless Mrs. Holland (Dame Julie Walters), who is willing to kill to get her hands on it.

Sally Lockhart (Billie Piper) now runs her own financial consulting business, while her friends Frederick Garland (J.J. Feild) and Jim Taylor (Matt Smith) have opened a detective agency. But when one of her clients loses money over a vanishing steamship, Sally and the young detectives join forces again. The mystery leads them to a threatened stage magician and a medium with a dark vision. Sally must also face an old enemy.
