With his father in a coma, CIA operative Samuel Tolen may have found a way to answer mankind's greatest question: Is there life after death?

When the Sudarium of Oviedo-the venerable cloth that once covered Jesus Christ's face on the cross-is stolen from a cathedral in Spain, it sparks a series of grisly murders. Each victim is killed in a manner resembling the form of execution of one of the Apostles. American CIA operative Samuel Tolen, Spanish inspector Pascal Diaz, and British archaeologist Dr. Jade Mollur embark on a journey to reclaim the Sudarium. Their search takes a surprising turn when a 2,000-year-old clue from Joseph of Arimathea suggests a far greater secret is within reach; a startling discovery that would forever change humanity.

Embroiled in a deadly hunt that takes them from the grounds of Harvard University to the coast of Costa Rica, from a hallowed Greek Isle to an exquisite Spanish cathedral, and ultimately to the doorstep of mankind's greatest civilization, Tolen, Diaz, and Mollur will search for the ultimate truth in the midst of unspeakable deception. But is it a truth mankind was meant to discover?

"Dan Brown better look over his shoulder - Williams and Knerly are here for his crown. Indisputable Proof is an edge-of-the-seat thriller with great storytelling backed by brilliant research."
