After a fire tears through the library of an ancient monastery a medieval script is discovered hidden behind an antique bookcase. Badly damaged, it is sent to Paris for restoration and there literary historian Hugo Pineau begins to decipher the startling fourteenth-century text. Within its pages lies a fanciful tale of a painted cave and a rudimentary map. Intrigued, Hugo enlists the help of archaeologist Luc Simard and the two men embark on a journey that will change the course of their lives forever.

When Luc and Hugo discover a vast network of prehistoric caves, buried deep within the cliffs, they realize that they’ve stumbled across something extraordinary. And at the very core of the labyrinth lies the most astonishing chamber of all, the tenth chamber. 

Aware of the significance of their discovery, they set up camp with a team of experts, determined to bring their find to the world. But as they begin to unlock the ancient secret the cavern holds, they find themselves at the center of a dangerous game. One ‘accidental’ death leads to another and it soon becomes clear that someone or something will stop at nothing to protect the secret of the tenth chamber.

Will Piper

Library of the Dead

The most shocking secret in the history of mankind is about to be revealed...A murderer is on the loose on the streets of New York City: nicknamed the Doomsday Killer, he's claimed six victims in just two weeks, and the city is terrified. Even worse, the police are mystified: the victims have nothing in common, defying all profiling, and all that connects them is that each received a sick postcard in the mail before they died - a postcard that announced their date of death. 

In desperation, the FBI assigns the case to maverick agent Will Piper, once the most accomplished serial killing expert in the bureau's history, now on a dissolute spiral to retirement. Battling his own demons, Will is soon drawn back into a world he both loves and hates, determined to catch the killer whatever it takes. But his search takes him in a direction he could never have predicted, uncovering a shocking secret that has been closely guarded for centuries. 

A secret that once lay buried in an underground library beneath an 8th Century monastery, but which has now been unearthed - with deadly consequences. A select few defend the secret of the library with their lives - and as Will closes in on the truth, they are determined to stop him, at any cost...
