Episode 1

Lucy Worsley takes on the case of a forgotten Victorian serial killer who was never caught. Dubbed the Thames Torso Murderer, and operating at the same time as Jack the Ripper, this killer’s hallmark was to dismember the bodies of his female victims and scatter the body parts in and near London's Thames River.

Now, Lucy, with the help of a team of historians and writings, is investigating this historic cold case, re-examining leads that were followed and uncovering new ones, with the ultimate aim of unmasking one of the 19th century’s most brutal serial killers.
