chunk: The next day, two men (who are drug dealers) arrive at the apartment to pick up the package. Peter and Michael mistakenly give Mary to them instead, and shortly after they leave, Peter discovers the actual package. He runs downstairs to intercept them, but trips and stumbles, and the package's contents spill. He gathers it and retrieves Mary from them, but retains the heroin while allowing them to take a can of powdered milk. After the exchange, a police officer attempts to ticket them for illegal parking, but they escape. He accosts Peter and detains him in the apartment until Sgt. Melkowitz (Philip Bosco), a narcotics officer, arrives to question him and Michael about the drugs. They successfully hide them from him during the interrogation, in which they learn that Jack's friend is a drug dealer as well. He leaves with suspicions and puts them and the apartment under surveillance.
