Brooke Adams, the wife of Monk star Tony Shalhoub, appears in this final episode of the series' third season as Abigail Carlyle, the mother of violin prodigy Daniel Carlyle...and a key player in a bizarre extortion plot. Monk is called in to investigate after a 22-month-old kid named Tommy (played by twins Preston Shores and Trevor Shores) shows up carrying a severed human finger in his tiny fist. The clues lead Monk to deduce that the finger belonged to a violin player, and this leads him to a meeting with the Carlyles. It doesn't take long for Monk to realize that "Daniel Carlyle" is an impostor, and that the real Daniel has been kidnapped--and to top it off, THIS crime is inextricably linked to little Tommy's grisly discovery. ~ Hal Erickson, Rovi
