London 1888: A brutal serial killer is terrorising the population of London's East End. The police are unable to prevent his crimes, which increase in cruelty and perversity from murder to murder. Who is this unknown killer, who strikes on busy streets without leaving a trace? A very personal motive prompts consulting detective Sherlock Holmes to make his own investigations. Can he succeed in stopping the gruesome series of murders? The "Secret Cases of the Master Detective" started out as a series of audio dramatisations from the award-winning producers TITANIA MEDIEN which bring to life exclusive stories surrounding the master detective Sherlock Holmes and his companion and chronicler Dr Watson. Now these exciting cases of the popular detective duo are being published in book form as a series of self-contained stories encompassing both new and previously recorded cases.
