Doc Alibi!

This is a character of mine named Doc Alibi. You go to him if you've done a murder or something and you need a water-tight alibi constructed. As a concept I think it's a solid basis for an ongoing series, with a new client each story laying the basis for the plot to come. Often it is the opening of an adventure that is the most difficult to make believable. Also I really like the idea of a story that is not about the 'hero' or the 'villain', but a middle-man doing his job really well!
