Solitaire (comics)
Solitaire is a crime-fighting superhero. He uses detective skills and a network of street-level informants to wage a one-man war on crime a la DC's Batman. He is not, however, without superpowers, as Batman is. Solitaire has a rapid healing ability (like Marvel's Wolverine) which allows him to recover from stab wounds, gougings, and even gunshots.
