PLAINCLOTHES was a Dick Tracy tribute website created by writer Mike Curtis and artist Joe Staton, with technical advice and additional material by Sgt. Jim Doherty. The site featured their version of a Dick Tracy strip, entitled "Major Crime Squad", as well as some other Tracy-related works.
This unlicensed work attracted the attention of Tribune Media Services, who hold the publishing rights to the Dick Tracy character. This eventually led to Curtis and Staton being offered the position of creative team on the official strip, upon the retirement of Dick Locher. The site has since been taken down.
The storyline featured on the PLAINCLOTHES site was later re-worked into Curtis & Staton's first official continuity on the strip, which featured the return of Flyface and Willie the Fifth.
