A Shadowline Saga: "Critical Mass" #2

In "Foreword," the second issue of *A Shadowline Saga: Critical Mass*, Professor Clerk sets his apocalyptic plan in motion, using a long-embedded agent to eliminate key scientists—framing their deaths as suicides. With the world's brightest minds under threat, Doctor Zero is drawn into the mystery, teaming up with his ally Gregor to uncover the truth behind the escalating conspiracy. Written by D. G. Chichester and Margaret Clark, with art by Mike Manley and colors by Steve Buccellato, this 1990 Marvel release features a tense, high-stakes thriller grounded in paranoia and hidden agendas, all wrapped in a striking cover by Mark Texeira.
