Hunted Along the Rhine

Secrecy and tight security measure are essential when Mark, Penny, and David travel to Dusseldorf, Germany, on a mission for Mr. Daring's company. But tapped phone lines, hidden TV cameras, a crossbowman, and a band of neo-Nazis make their assignments difficult and dangerous. Mr. Daring's banker, Herr Rosen, is blackmailed by communist agents, and the teens have incriminating information in their possession. They suspect that their archenemy, Hoffman, is involved in this underhanded scheme. Join Penny, Mark, David, and Rosen as they try to outsmart their adversaries in an unbelievable, bullet-flying speedboat chase on the crowded Rhine River.
