John Turturro returns in the role of Ambrose Monk, the agoraphobic older brother of obsessive-compulsive detective Adrian Monk (Tony Shalhoub). In the middle of a murder investigation, Monk is summoned to Ambrose's home for a possible reunion with the boys' long-lost father. Upon arrival, Monk is hit squarely between the eyes with another mystery, this one involving a Halloween trick-or-treater who resorts to violence to get something more than candy. Ingredients essential to the action are a dead pigeon, a poisoned chocolate bar, and a real-life Frankenstein monster! ~ Hal Erickson, Rovi
