POSTSTRASSE 16 tells the story of a young college graduate anxious to succeed in the fast-pace world of internet entrepreneurship who commits to a business relationship not knowing the dangers it poses. Claire Berman is a twenty-seven year old Harvard educated woman who possesses special skills in the hot new field of crowd-sourcing analysis. Working out of a dot-com incubator in Alexandria, Virginia, she's approached by Lawrence Appleton, who identifies himself as a representative of the Clearfield Institute of New York City. The Institute's mission, he explains, is to promote world peace through assisting governments in Eastern Europe in their fight against smuggling. Stopping off in Berlin, Germany, after a brief business trip to Belgrade on behalf of the Institute, Claire visits her grandmother, Alice Marckwald, who lives there after gaining possession of an urban mansion in a restitution claim shortly after the unification of East and West Germany. The visit becomes open-ended as she doggedly pursues the objectives of the Institute using her crowd-sourcing expertise. Gradually, she discovers the true identity of her employer and the full extent of the danger she's been exposed to. The action is fast-paced, with Claire finding herself buffeted by criminal threats as she pursues her work through the capitals of Eastern Europe.
