"Detective Nick Belsey, a shrewd, street-smart cynic and dedicated drunk who is also one of London's sharpest and most unprincipled investigators, was introduced in 2012's The Hollow Man; now he's back in another gritty, white-knuckle thriller. Trouble once again finds Nick Belsey when he takes a date to an abandoned bomb shelter buried beneath the heart of London. One minute the young woman is there, and the next, she's gone, mysteriously vanishing into the dark labyrinth of secret tunnels. A seasoned cop with a bad reputation, Nick knows that if he reports her disappearance, he'll be the prime suspect. Instead, he's going to find her. It's not just her life at stake it's his, too. Determined to discover who is down in those forgotten tunnels and how far this secret network of underground passages extends, he plunges headfirst into the investigation and into a dangerous game of cat and mouse with a ruthless enemy who would rather let an innocent woman die than reveal Cold War secrets."--Publisher.
