In Showcase #78 (1968), a 12-cent dive into noir with a touch of myth, Marv Wolfman and Joe Gill introduce Jonny Double—a weary ex-cop turned private investigator who’s less knight in shining armor and more a man in borrowed, tarnished steel. Drawn into a case by a mysterious call about his twin brother’s murder, Jonny navigates a world of shadows, cigarette smoke, and cheap favors, all while dodging thugs and being paid in quarters. Jack Sparling’s moody art and Dick Giordano’s sharp cover bring this downbeat, hard-boiled tale to life.

Jonny Double, a weary ex-cop turned private investigator, wakes to eviction and a new case: a murdered syndicate man whose twin brother might hold the key. With a meager retainer and a pocket full of borrowed cigarettes, he dives into a world of shadows, chasing leads that leave him bruised and broke—paid in quarters, not answers.

Jonny Double, bruised and down to his last chance, finds unexpected kindness from Crys Cross, the blonde waitress with a sharp eye and a softer heart. When he tracks down the mysterious Mr. Twain’s brother—tied to two seemingly respectable businessmen, Piker and Glass—he’s turned away, but not before slipping into their office in disguise as a janitor. What he overhears in the quiet of the office could be the key to the case, but his luck—so far, nothing more than dumb, stupid luck—finally runs out when he’s caught. Now, with no place left to hide, Jonny’s dragged to the roof, the city sprawled below, and the edge just steps away.

[Meet Jonny Double!..] Chapter 3
6 pp · Detective-Mystery

In "Meet Jonny Double!.. Chapter 3," the quick-witted detective dodges a deadly fall, then flees through an eerie amusement park, only to find himself cornered in the twisted Hall of Mirrors. With bullets flying and shadows closing in, Jonny Double faces off against a relentless pursuer in a fight that’s as sharp as it is surreal. The barker’s final, cheeky photo proves the night’s chaos wasn’t just survival—it was a show.

[Meet Jonny Double!..] The End.. Plus One...
0.5 pp · Detective-Mystery

Jonny Double’s latest case ends with a stubborn sign painter demanding payment—and a cryptic warning that this isn’t the end. As Jonny vows not to be a loser anymore, the weight of his past and a sudden shift in the mood of the streets hint at something more than just a missed paycheck.
