Erik Hoopen’s “Oversea Travel Agency” in Hamburg fronts an international gold‐smuggling ring. Couriers hide gold bars in special vests, exporting them to black markets in Cairo, Khartoum, Hong Kong, and Singapore and returning with suitcases of cash. Fierce underworld competition leads to thefts and murders. Central to the intrigue is mysterious locker #763, tying the criminal network together.
