Just when you think you know... you realize you don't even understand the question.

Award-winning author Arnaud Pascolo delivers a gripping international crime thriller that begins with a death -- and unfolds into a mystery so intricate, so unexpected, that nothing is what it seems. If you enjoy Daniel Silva, Stieg Larsson, or Michael Connelly, you'll love Zero Knowledge

"The storyline was fast-moving, and I found myself unable to turn the pages quickly enough, fearful that I would miss something important." -- Alma Boucher for Readers' Favorite ?????

When crypto entrepreneur Luc Starck receives a mysterious text message promising a solution to his failing company, he agrees to a meeting in Switzerland's Crypto Valley. He leaves with an envelope labeled "Clue One." Minutes later, after answering a phone call, he collapses and dies without warning.

At first, it appears to be a tragic natural death. Then the clues begin to surface.

As the investigation intensifies, senior investigator Bernt Berg and his ambitious rookie daughter are pulled into a case that refuses to follow the rules. Each answer leads to more questions. Each clue reveals a deeper layer of deception. And soon they realize they aren't just trying to catch a killer --

They're trying to figure out what the crime actually is.

Meanwhile, Duan Ripa, a grieving widower and cryptography expert, begins decoding the private key to Luc's crypto wallet and uncovers a terrifying truth: Luc's death was only the beginning. Hidden within encrypted clues is a deadly game already in motion, and the clock is running out.

Set in the real-world crypto capital of Zug, Switzerland, Zero Knowledge is a fast-paced, intelligent thriller filled with cryptography, secrets, revenge, and a mystery that twists until the very last page.

Because sometimes the perfect murder isn't about hiding the killer... It's about hiding the crime.

"Deeply rooted in reality, the word-building of this narrative skillfully conveys the excitement of anonymity. Its capacity to defy genre boundaries is evident as it reads as literary fiction at first, then as a cyber thriller, and lastly as a revenge story."-- The Feathered Quill ?????

"Zero Knowledge is an exciting thriller by Arnaud Pascolo that skillfully weaves together a complicated and high-stakes story involving crime, technology, and personal drama. This book is a masterpiece of modern storytelling." -- Jessica Morgan for The Book Revue ?????
