The Tenth ChamberBook - 2010
In The Tenth Chamber, Glenn Cooper introduces us to a new hero, Luc Simard, an archaeologist with a flawless academic career and a flawed history with women. When a book dating to the fourteenth century is found after a fire in a monastery in the Perigord region of France, Luc's old friend Hugo calls him in to help decipher the mysterious illustrations that dot the coded manuscript. The illustrations remind Luc of the cave paintings the Perigord region is famous for, but neither man can make any sense of the text's message, save for the fact that it claims to be written by a 200-year-old monk.
What Luc and Hugo do find in the manuscript is a map that leads them to a ten-chambered cave that is beyond their wildest expectations. The cave's walls are painted with images far more detailed and advanced than those at Lascaux, yet there are clues that suggest this cave is more than 10,000 years older. Theirs is the discovery of a lifetime. The secret of the cave lies in the coded pages of that fourteenth-century manuscript, but it's a secret that someone is willing to kill to protect.
