Twin Peaks

FBI Special agent Dale Bartholomew Cooper is a fictional character from the television series Twin Peaks, portrayed by Kyle MacLachlan. He is the lead protagonist of the series and also briefly appears in the prequel film Twin Peaks: Fire Walk with Me.

Cooper is an FBI agent who arrives in Twin Peaks to investigate the brutal murder of the popular high-school student, Laura Palmer, falling in love with the town and gaining a great deal of acceptance within the tight knit community. He displays an array of quirky mannerisms such as giving a 'thumbs up' when satisfied, sage-like sayings, distinct sense of humor, along with his love for a good cherry pie and a "damn fine cup of coffee". One of his most popular habits is recording spoken-word tapes to a mysterious woman called 'Diane' into his microcassette recorder that he always carries with him, that often contain everyday observations and thoughts on his current case.
