Mr. Monk Gets a New Shrink (S05E07)

Early one morning, Dr. Kroger's cleaning lady is found stabbed to death in Kroger's office, and the police suspect that one of Kroger's patients could be the culprit. Consumed with the thought that one of his patients would commit murder, Dr. Kroger retires, sending Monk into a complete tailspin and out to uncover what really happened to the cleaning lady. (iTunes)
