Catherine's (Cindy Williams) world is turned upside down after her seemingly perfect husband, Donald is murdered in the flat of prostitute Marla (Markie Post). Turns out Donald has been involved in some shading doings and Catherine and Marla have to team-up to get to the bottom of it before a gang of killers get to them. This is a mild and occasionally amusing made for TV effort. It has a fairly naïve view of prostitution and crime, but you wouldn't really anticipate otherwise. Cindy Williams and Markie Post make for a nice team as the odd couple from different sides of the tracks. The comedy is slight and inoffensive; the story patently ridiculous and the direction workmanlike. All that said "Tricks of the Trade" still makes for a mild and likable little comedy. ( )
