The Tigris Leaps

PERRY RHODAN gives a command!Maj. Clyde Ostal, an experienced officer of the Solar Security Service, is to take Responsibility for the armed spacer Tigris. His mission, together with 31 picked men: to leave Earth in the ship in a deliberate attempt to learn whether the Robot Regent of Arkon can detect the frequencies of structural compensators and thereby determine the position of spaceships going through hypertransition.  In 2042 the Positronicon that rules the Arkonide Empire does not yet know the location of Earth—and Perry Rhodan wants to keep it that way. Hence, Maj. Ostal's important mission.  You're in for a wild time when—  THE TIGRIS LEAPS!
