Behind the Glass is a thrilling detective novel that blends elements of mystery and modern technology. When historian Arthur Pendelton is found dead in a perfectly locked room amid the thick fog of Blackwood Valley, detective Grayson Walker is drawn into a seemingly unsolvable case. Disappearing traces, tampered surveillance data and forgotten ancient tunnels under the town reveal a dark conspiracy that has been buried for more than a century. The closer Grayson gets to the truth, the more he realizes that the threat comes not only from a clever murderer, but also from ancient secrets rising from beneath the foundations of Blackwood Valley.
