 Who does Jig suspect wants them dead, and let loose the vapor snakes?
The Blue Behemoth By LEIGH BRACKETT Shannon's Imperial Circus was a jinxed space-carny leased for a mysterious tour of the inner worlds. It made a one-night pitch on a Venusian swamp-town—to find that death stalked it from the jungle in a tiny ball of flame. It was Gow, our zoo-man—a big, ugly son-of-a-gun from a Terran colony on Mercury. Bucky Shannon walked out into the glare of the light at the entrance to the roped-off space around the main lock.
