The Ultimate Vampire Resource and Directory

Lucky Starr and the Rings of Saturn is the final novel in the Lucky Starr series, six juvenile science fiction novels by Isaac Asimov that originally appeared under the pseudonym Paul French.

Six weeks after returning from the Jovian system, David "Lucky" Starr receives an urgent visit from Hector Conway, Chief Councilman of the Council of Science. The Council has been sweeping up the Sirian spy ring uncovered by Starr in the Jovian system, but the head of the ring, Jack Dorrance, has eluded capture and escaped from Earth in his one-man spaceship, The Net of Space. A fleet led by Councilman Ben Wessilewsky is in hot pursuit, but there is only one ship that can catch up with Dorrance, and that is Starr's own Shooting Starr.
