A series of unexplained deaths. A popular new video game. Could the two be linked?

One Sunday morning, Detective Inspector Auguste Allinson receives a call from his trainee partner from the local hospital, where a senior doctor has expressed concerns regarding an increase in unexplained deaths.

Allinson is due for retirement but, trying to delay its arrival, decides to take on the dead end case – but what seemed like a simple case to crack turns out to be more complicated than he could have ever imagined. His investigations lead him to a games company, an online role playing computer game, and the virtual town of Saltwitch.

After several more deaths, a meeting with a mysterious suited man and a close escape on Dartmoor, Allinson is forced to play the game for real, but who can he trust in this virtual world? Can he find the murderer? Can he stay alive?
