Jessica Fletcher - Manhattan - Gyilkos sorok 2.

Jessica Fletcher, the well-known crime writer, is coming to Manhattan to promote her latest book. According to his plans before Christmas, in addition to the autographs, he can still fit in a little sightseeing, shopping, visiting his favorite restaurants... but what about solving a murder case?
While walking in the Christmas rush, he notices that a man in a Santa costume looks him straight in the eye - and he immediately recognizes him: the ex-drug dealer he's seen for a long time is the one everyone back home in Cabot Cove knows well. However, before they can meet again, to indulge her curiosity and find out what the man is doing there, Santa is murdered in front of her.
Believing the police to be floundering, Jessica takes the investigation into her own hands.
