From the back cover:
Secret Agents from all over the world are converging, clandestinely, on a small science fiction convention. Coded transmissions have been intercepted, emanating from somewhere near the Con Suite. Fans have mysteriously disappeared, and strangers have shown up at the convention wearing their badges. And rumor has it that some of these clever costumes aren't really costumes at all.
