It is late spring, 1978. Poincare has worked to near-exhaustion preparing for the Lutine dive. Before the salvage season begins, he takes a rare holiday: a hike at low tide across the vast, muddy flats of the Wadden Sea. His guide is Liesel Kraus - smart, able, appealing...and troubled. She and her brother Anselm, directors of Kraus Steel, are haunted by a violent history that generates both rage and an enormous, corrupting wealth. The closer Poincare draws to Liesel and Anselm, the more warped life becomes until love and a death threat compel him to investigate what no one else - aside from Interpol - will. Pain as well as treasure, he discovers, can be dredged up from the past to reshape the present.
The Tenth Witness, a prequel to the award-winning All Cry Chaos, is the tale of a man upended: a twenty-eight year old who rejects a brilliant career in engineering for an uncertain, darker one: international police work.
