‘One of British crime writing’s hidden jewels’ Time Out Megan Harpur had taken the train back from London to tell her husband she was leaving him for another man. By the time Detective Chief Superintendent Colin Harpur discovered her in the station car park in the early hours of the morning, there was nothing anyone could do. Who had committed this savage killing? And what did Megan’s lover’s secret activities have to do with it? The crime confronts Harpur with the most unnerving case of his career — an investigation into his own wife’s brutal and apparently senseless murder.
