Were 400 Roma massacred in the last days of the Bosnian war and buried by an explosion that collapsed a coal mine? Attorney Bill ten Boom leaves his life in Kindle County behind to work for the International Criminal Court in The Hague and to investigate that question. The testimony in the title belongs to one Ferko Rincic, who claims to be the only survivor of the massacre. Twists and turns abound in this well-crafted legal thriller. Ten Boom finds love, danger, friendship, and explores his own family’s history. I hope that we hear more from ten Boom and his work in The Hague in the future.
