Reasonable Doubts is an American police drama television series created by Robert Singer, which broadcast in the United States by NBC that ran from September 26, 1991, to April 27, 1993.

Reasonable Doubts is primarily about the working relationship between Assistant District Attorney Tess Kaufman (Marlee Matlin), a prosecutor very sensitive to the rights of the accused, and hard-charging, gruff Detective Dicky Cobb (Mark Harmon), an old-fashioned cop with a "bust-the-perps" attitude. The reason that these two are assigned to work together was that Cobb is one of the few available police officers who knows sign language, and Tess, like the actress who portrayed her, is deaf. Dicky is usually more frustrated by Tess' sympathy for the suspects than by her deafness; he also repeats what Tess says back to her to make sure that he understood it (Tess can also read lips) and this allowed the audience to understand her part of the dialogue. Dicky also spoke as he signed to Tess.

Both characters are romantically involved with other people when the series opens: Tess is estranged from, but still in contact with, her husband Bruce (Tim Grimm); Dicky had a manipulative girlfriend named Kay Lockman (Nancy Everhard), who is, unsurprisingly, quite jealous of Tess, and not without reason, as a considerable mutual attraction, despite their differences, has developed between Tess and Dicky. The situation becomes more complicated with the death of Kay early in the second season, freeing the characters to pursue the relationship at least somewhat, although its resolution is still up in the air when the program was not renewed for a third season. Cobb was also involved with flinty lawyer Maggie Zombro (Kay Lenz), an early continuing character who became a regular in later seasons.^[1]

Executive producer Bob Singer gained some interest from the network in spinning off the show into a straight cop drama starring Harmon and Jim Beaver, who had played Dicky's friend and partner Detective Earl Gaddis from the beginning of the show, but ultimately NBC demurred.
