Sam Spade and Philip Marlowe were tough guys, but I don't know if they would have made it as detectives in the Marvel universe. 
 Ex-superhero turned private investigator Jessica Jones takes a case involving a missing teenage girl in a small town, and there are rumors everywhere that she was a mutant. Finding the girl will be a lot easier than dealing with the racism and small minds Jessica encounters while on the trail, but she manages to find time to work in her self-destructive hobbies of binge drinking and casual sex with men she just met. After that she has a rather awkward encounter with Luke Cage, and tries to do something normal like go on a blind date. Of course, she was set up by her friend Captain Marvel, and the guy is Scott Lang, a former Ant-Man, but hey, it's as normal as things get for Jessica. 
 Alias continues to impress with it's messy depiction of what life might be like for someone with superpowers who doesn't want to put on a cape, and Jessica is exactly the kind of regret filled boozy detective who populates many a good crime novel. I especially enjoyed one sequence in which the usual muddy and nearly ugly art is changed to to the bright clean lines and colors of a more traditional Marvel comic when Jessica is dreaming of her days flying around in tights. It's a great visual representation of how Jessica used to see herself versus how she currently feels.
