Dark waters hide deadly secrets.

When the headmistress of a Portsmouth school is found brutally murdered on an old structure in the middle of Langstone Harbour, Detective Andy Horton of Portsmouth CID is assigned to the case. The victim, discovered with a note with the words ‘Have you forgotten ME?’, was a steely, determined woman who made enemies on her path to success. But did any of them hate her enough to want her dead?

With the clock ticking and Superintendent Uckfield pressing for results, Horton is forced to make a decision that will put his life on the line.

This absolutely gripping detective mystery is perfect for fans of Ann Cleeves, Joy Ellis, and Rachel McLean.

THE DETECTIVE DI Andy Horton’s mum walked out on him when he was a child and he grew up in children’s home. Now he lives onboard his yacht in Southsea Marina. He rides a Harley-Davidson and never wears a suit or tie — unless it’s to go to court. He’s an instinctive copper and a man of contrasts, which often lands him in trouble with his bosses. He has a desperate need to belong, and yet is always just on the outside. Self-contained, afraid to show his feelings, but he’s a risk-taker that seeks justice.

THE SETTING Portsmouth boasts a vibrant waterfront, a diverse multicultural population, an international port, a historic dockyard, and is home of the Royal Navy. Portsmouth Harbour is one of the busiest in the world — and one of the best places to hide a body, it seems. Set against the backdrop of the sea, the Solent area of Portsmouth and the Isle of Wight is every detective’s worst nightmare. The sea is ever-changing and often the best clues get swept away by the tide.
