Born in Brooklyn, New York, Linker's first major acting role was as Kelly Lewis in the television series Lewis & Clark, which ran for one season from 1981 to 1982. Shortly thereafter, Linker was cast as central character Lauren Hutchinson on the teen comedy/drama Square Pegs. Square Pegs told the story of two high schoolfreshmen, Hutchinson and Patty Greene, and their at times desperate attempts to fit in and achieve popularity. Linker was forced to wear fake braces and a fatsuit in order to appear less attractive than she actually was for the character she portrayed. Even though the show was praised by critics, it was cancelled after its first season. Square Pegs creator Anne Beatts revealed the show's abrupt demise came from unfortunate circumstances behind the scenes - specifically, drug abuse among the teenage cast. Beatts revealed in 2015, "I think that certainly, there was some drug abuse or drug traffic that may have happened, because I would say that that is the norm for a set". Devo member Gerald Casale also confirmed in 2009 about the drug use on set, saying "The girls were out of control — they were doing drugs and they were making out and they were coming on to us in a big way... They might have been 15 or 16, but in their heads they were already 40. I don’t think there was a virgin on the set, except maybe a couple of the guys". Most of the show's scenes were filmed at the abandoned Excelsior High School in the suburb of Norwalk, California. Because Norwalk was twenty miles from Norman Lear's studio and CBS Television in Los Angeles, it was hard to know what was happening during filming. Embassy Television received numerous reports of drug and alcohol abuse in the presence of minors, which caused then Embassy president Michael Grade to ask for an investigation and led him to pull the plug on the show shortly after the first season finished production. After Square Pegs, Linker voiced the character of "Robin" on the animated Mister T series in 1983. After the show ended she enrolled in Wellesley College, graduating in 1989 with a degree in French studies. Other notable roles for Linker were as Sherie Lee Fox in the 1985 science fiction filmD.A.R.Y.L., and as Jenny Pennoyer in the 1984 TV movie When We First Met. Most recently, Linker appeared as the character Esmerelda on the television series Don't Make Me Sick in 2009.
