An American millionaire, Joseph Barkley, appears at the detective agency of Klim Ardashev in Prague. The visitor complains that, even back in New York, he was blackmailed and extorted by a certain Morlock. The culprit sent the banker a life price list for the coming month. Joseph Barkley asks to find the criminal who has started a deadly game—now even in Europe. How does Morlock kill at a distance? That is what private detective Klim Ardashev will have to figure out, while continuing to investigate the smuggling of the tsar’s gold through Tallinn and Stockholm at the same time.
