The last train of the night pulls into the gas-lit platform of Baker Street underground station. A young woman is found strangled, her body abandoned in a second-class carriage. The brutal 'Railway Murder' brings Inspector Decimus Webb to the newly-formed Metropolitan Line on a bleak winter's night. His investigation leads him through the slums of Victorian London to the Holborn Refuge, a home for 'fallen women', and to Clara White, a respectable servant. But Clara has her own tragic and shameful history. As her past is revealed, Inspector Webb must decide whether she is merely a victim of circumstance, or a prime suspect. Only then can he unearth a dark secret, hidden in the depths of underground London.

Lee Jackson's second novel brilliantly recreates the sights, sounds and smells of Victorian London, taking readers on a suspense-filled journey through its criminal underworld.
