Monk is a Detective Drama that aired on USA Network from 2002 to 2009. The show is about Adrian Monk (Tony Shalhoub), a former San Francisco police inspector who suffered a nervous breakdown after the murder of his wife, Trudy. He is a lifelong sufferer of Obsessive-Compulsive Personality Disorder and has many phobias, and those obsessions became crippling after his breakdown, forcing his retirement; he recovers throughout the series, though he is never fully "cured". His OCPDnote is also the reason Monk was such a successful policeman; one of his compulsions is paying amazing attention to details.
Thanks to his breakdown, Monk was discharged from his department, but is frequently called in to consult on cases which baffle the police, often some kind of Locked Room Mystery, by his friend and former commander Captain Stottlemeyer (Ted Levine). His disorders are part and parcel of his unique mind; without them, he wouldn't be able to solve these cases. Of course, the one case Monk's been trying to solve since his breakdown is Trudy's murder, and each season of the show brings him a little closer to finally solving the mystery behind her death (with the show's final season bringing the case to a close for good). Meanwhile, Monk is assisted in his investigations by his former nurse Sharona Fleming (Bitty Schram), and, after Sharon's departure in the third season, by Natalie Teeger (Traylor Howard).
Monk is notable for subverting pretty much every Perp Sweating convention; due to Monk's disorder and the invariable intelligent cockiness of the bad guy, he's always the one in any round of questioning who's uncomfortable and making mistakes. Of course, many of the comedic situations in the series would not exist if Monk or one of his friends would simply explain his issues to others. So they don't. However, despite the perpetual comedy at his expense, he is largely portrayed sympathetically. Viewers come to believe that his condition is, as Monk himself puts it, "a gift... and a curse".
This show was a turning point for the USA Network. USA was previously a channel with a lineup consisting mainly of reruns, cartoons, game shows, Wings (which incidentally also starred Tony Shalhoub), WWE programs and low-to-middling quality original programming (and, of course, Duckman). Monk was the first major hit show for the network, launching what has become a string of popular, critically-acclaimed series.
Not to be confused with the Gothic novel, which is about an actual monk.
Unless I'm wrong, which, you know, I'm not, this show provides examples of the following tropes:
Note: Monk spawned a book series which currently consists of 19 novels. Examples for it are also found in trope list.
