Lieutenant Disher is Captain Stottlemeyer's eager but bumbling right-hand man. Ambitious, well-intentioned, and devoted to the Captain, Disher is a faithful "Boy Friday." Though competitive and even a little jealous of Monk, Disher lacks brilliance as a detective. Yet his eagerness to please and naïvete is endearing, and despite his often wacky theories and techniques, Disher remains an integral part of the crime-solving team.
