Name: O'Malley, Jack O'Malley
Gender: Of the more masculine and hard boiled persuasion
Age: Old enough to know better, kiddo. Not like it matters in this biz, anyway.
Appearance: Well I've seen better days. The booze and smokes have certainly taken a toll on the mug, but I like to think I'm still an attractive member of the male species. Got that hard boiled, stubbly look that the dames love. Don't go anywhere without my fedora and trenchcoat though. Not to mention the six shooter.
Bio: How'd I get into the biz? Kid, that's a long story that you don't wanna hear and I don't wanna tell. Too much heart break all around. Suffice ta say I know some people, and I'm the best damn Private Dick you'll ever meet. Heh. Private Dick. Some things never get old. Anyway, I knew some people in high places, and this job's a lot like my last one--but it pays more, and I get to relive the glory days of last week. How could I say no?
Specialty: Well, I'm a pretty good shot with my six shooter if I do say so myself. Sure, it's a relic, but I like it. It's got a few upgrades, anyway, so it's not all bad, and the Python never goes outta style, kiddo. Other than that, ain't no one better at casin' a case, than old O'Malley. That's why I got the job after all.

Basically
this guy plus a few years and some stubble.
Miiiiight be a bit too hard boiled P.I. for this, but it's the first thing that came to mind, and that's how I roll.
