Bring On the Back-ups: "Return to Destiny" by O'Neil, Netzer, and Austin

Season's Greetings, Groove-ophiles! A couple'a weeks ago, we dug on the first chapter of Denny O'Neil, Michael Netzer (then Mike Nasser), and Terry Austin's mighty Martian Manhunter mini-epic (right here). Today we're gonna check out the second sensational chapter, this one guest-starring Supergirl! A sci-fi murder mystery with totally cool, unique, and awesome art? Yeah, baby, that's what we've got right here! From Adventure Comics #450 (December 1976), here is "Return to Destiny"!
