<P> CBS executives hoped Gless would portray Cagney as more conventionally "feminine" and attempted to pressure the producers to remake Christine into a more "high - class", snobbish woman from wealthy parents . Barney Rosenzweig and Barbara Corday initially refused to change Christine Cagney from a tough, witty, working - class woman . Shortly into Gless's tenure on the program, Rosenzweig and Corday compromised with the network brass . They further developed Cagney's background, explaining gradually in a loose storyline that she may have been born to a somewhat well - to - do professional mother, who had a relationship with police officer Charles Cagney who came from working - class roots . Charles and Maureen soon separated after Christine and her brother Brian were born . She was partially raised in an uptown Westchester world, which she appreciated; however, the trappings of the upper - middle social strata sometimes drove her to miss her father's lifestyle, and she and her father therefore established a special bond . </P> <P> Cagney was a bit quieter and more reserved than her vivacious, talkative, loud partner Mary Beth Lacey, but could still relate to the world with attitudes that could be shared by people across the social spectrum . </P> <P> Al Waxman co-starred as Cagney and Lacey's good - natured and sometimes blustery supervisor, Lt. Bert Samuels . Carl Lumbly and Martin Kove played, respectively, fellow detectives Marcus Petrie and Victor Isbecki . Sidney Clute played veteran detective Paul La Guardia . John Karlen co-starred as Mary Beth's husband, Harvey Lacey, and Tony La Torre and Troy Slaten played their sons, Harvey Lacey, Jr. and Michael Lacey, respectively . Harvey Atkin played desk sergeant Ronald Coleman . Jason Bernard originally had the recurring role of Deputy Inspector Marquette during the first two seasons . When the show was brought back in March 1984 following its second cancellation, Marquette had been replaced by Dep . Inspector Knelman (Michael Fairman), who lasted the duration of the series . In the fourth season, Christine entered into a relationship with Sgt . Dory McKenna (Barry Primus), who battled a drug addiction . After a tumultuous courtship, Christine left him and soon after took up with a more stable suitor, David Keeler (Stephen Macht), a local attorney . </P> <P> One of the most significant cast changes occurred early in the fifth season, upon the death of Sidney Clute in October 1985 . Off screen, Det . LaGuardia had retired from the 14th Precinct and had moved to New Jersey with a new female companion less than half his age . Clute had completed filming a few episodes of the 1985--86 season prior to his death . In his honor, the producers kept Clute's name in the opening credits for the rest of the series . </P>
