Showing In a Dark House by Deborah Crombie

A corpse, burned beyond recognition, has been uncovered in a vacant warehouse in Southwark . . . A young, beautiful hospital administrator has vanished without a trace, her past a mystery to even her closest friend . . . And across the City, within an old, dark, rambling house, a rigidly controlling, anonymous woman is holding ten-year-old Harriet hostage. While innocent lives hang in the balance, sinister truths unfurl and DS Duncan Kincaid and DI Gemma James must call upon all resources to work together on their most menacing case yet . . . ‘Deborah Crombie just keeps getting better and better. In a Dark House is utterly compelling’ PETER ROBINSON
