When a series of gruesome cult killings take place near the British Museum, DCI Harker and his assistant DS Critchley are called to London to solve the case. Middle class satanists, dusty old bookshops, a labyrinth under the museum, a frantic car chase and wry, cutting humour all combine in this love letter from creators Roger Gibson and Vince Danks to classic British detective television series.
