At the London Police Academy in the early 2000s, a mysterious figure known only as ‘S’ gives a lecture based on three cases from his archive of police tapes and old VHS footage, examining cyber crime and internet hoaxes. The lecture centres on an abandoned recording device discovered in the ruins of Undershaw, the former home of Sir Arthur Conan Doyle. Two boys who found the device have disappeared after uploading its contents online, while those who listen to the recording appear to suffer disturbing consequences. Loosely based on Sherlock Holmes stories including ‘The Sussex Vampire’, the play places Doyle’s characters and mysteries within the technology of the 1990s.

Rosanna Mallinson writes and directs the production. Her previous work includes Fire Burn: Macbeth, which Broadway Baby described as “disorientating, nightmarish and incredibly compelling”, Silhouette in the Smoke: Immersive Mystery, praised by Everything Theatre for its direction, and The Animator, described by Rev Stan as “quick, slick and endlessly inventive”. Mallinson is an immersive theatre maker whose work combines live performance with interactive and technological elements.

Richard Durning is composer and sound designer, with Clancy Flynn as set and lighting designer and Flo Wiedenbach as video designer. The production also features Korina Kokkali as movement consultant and an immersive website by Charlie Kelly.
