It is questionable as to whether or not the director and screenwriters had the story of Dracula in mind when they wrote and filmed Shadow of a Doubt. In the final scene, during Uncle Charlie's funeral, Charlie thanks Detective Jack for being someone to whom she could tell the truth about Uncle Charlie. However, it is Uncle Charlie who falls off the train, right in the front of a passing locomotive.

The train starts up and, as it begins to speed, Uncle Charlie tries to throw his niece off the train. Just before the train starts to leave, Ann and Roger disembark, but Uncle Charlie holds Charlie back. Roger, Ann, and Charlie board with him so that Ann and Roger can see his accommodations. The next day at the train station, everyone from Santa Rosa wishes Uncle Charlie a goodbye and thanks him for the good that he has done for the city. When Uncle Charlie sees Charlie wearing the ring, he makes a toast and announces that he is going to be leaving tomorrow. Before the revelers come home, she searches Uncle Charlie's room and retrieves the ring. After the second attempt on Charlie's life, she decides to stay home from Uncle Charlie's speech and get ready for the party to follow.
