This is an enthralling personal account of the secret Nazi project, Operation Bernhard, devised to destabilize the British and, later, American economies by creating and putting into circulation millions of counterfeit banknotes. A team of typographers and printers was pulled out of the rows of prisoners on their way to the gas chambers and transferred to the strictly isolated Block 19 in Sachsenhausen concentration camp. There they were presented with the enormous task of producing almost perfect counterfeits to the value of hundreds of millions of pounds sterling. These notes were to be dropped from bombers over London, with the aim of causing financial chaos. When the time came the Luftwaffe's resources were fully committed in other campaigns and theaters but some of the currency was successfully used to fund operations in Germany's secret war.
