Kate Marshall

Kate Marshall was a promising young police detective when she caught the notorious Nine Elms serial killer. But her greatest victory suddenly became a nightmare. 15 years after those catastrophic, career-ending events, a copycat killer has taken up the Nine Elms mantle, continuing the ghastly work of his idol. Enlisting her brilliant research assistant, Tristan Harper, Kate draws on her prodigious and long-neglected skills as an investigator to catch a new monster. But there's much more than her reputation on the line: Kate was the original killer's intended fifth victim....

When Kate Marshall finds the body of a young man floating in the Shadow Sands reservoir, the authorities label it a tragic accident. But the details don't add up: why was he there in the middle of the night? If he was such a strong swimmer, how did he drown? As Kate and her assistant Tristan Harper follow the evidence, they make a far darker discovery.

Kate Marshall's detective agency takes off when she and her partner, Tristan, are hired to investigate a cold case from more than a decade ago. Twelve years previously, a determined young journalist called Joanna Duncan exposed a political scandal that had major repercussions. In the fallout she disappeared without trace and was never found. When Kate and her partner, Tristan, examine the case files, they find the trail long cold, but they discover the names of two young men who also vanished at that time.

When Private Investigator Kate Marshall is rushed to hospital after being pulled into a riptide current in the sea, the near-death experience leaves her shaken. During her recovery, she befriends Jean, an elderly lady on the same ward. Jean tells the harrowing story of how her three-year-old grandson, Charlie, went missing 10 years ago during a camping trip on Dartmoor.
