What if you had the chance to uncover tangible evidence of the divine? How far would you go, what dangers would you brave, in pursuit of the greatest mystery of all? Four companions of varying beliefs, on a journey to the forgotten corners of Europe, are about to find out.On a desolate English moor, a team of scientists unearths a two-thousand-year-old wooden box, preserved in silver and inlaid with a map of patterned gemstones. A set of runes inscribed on the box claims the map is a pathway to God. In an attempt to decipher the map, a wealthy New Orleans collector assembles an unlikely team: a specialist in cultural antiquities who dabbles in the occult; a jaded attorney searching for meaning; a brilliant linguist who loathes organized religion; and a Catholic historian with a reputation for acquiring pieces no one else can or will. Shackled by secrets and hidden motives, pursued by a sinister religious order, driven by an insatiable desire for answers, the four companions trek across Europe as they search for a connection among the ancient sites revealed by the map. As the hunt for truth takes them deeper into the unknown, their lives and perhaps their souls in peril, they must determine whether the letterbox is part of an elaborate, centuries-old deception or the answer to mankind's ultimate questions. From critically acclaimed and bestselling author Layton Green, The Letterbox is a thrilling new mystery that weaves danger, exotic locales, breathless suspense, romance, and ancient secrets into the tapestry of an unforgettable novel.
