Though it was popular with critics, Andy Barker, PI didn’t catch on with many viewers. It was cancelled after just one season of six episodes. Here’s what happened in the last episode, titled “The Lady Vanishes.”
Simon and Andy are eating in Wally’s and he invites them back for lunch. He’s trying to sex things up with “Hoomus Hotties” and gives them holsters with shots of Hummus in them. When they’re finished eating, Lew pulls up, tells Andy to get in the car, and refuses to let Simon in.
Lew drives them to his old office of 27 years. Andy finds a picture of a young Lew with his former partner, Mickey Doyle (Edward Asner). It seems Mickey was the reason that Lew left the force. He tells Andy that Mickey once tracked a guy down on his honeymoon and beat him to death with an ice bucket.
