Marjorie (The Secret Adversary)

In the novel The Secret Adversary, Marjorie is a person named on a list of survivors of the Lusitania. Tommy and Tuppence were searching for a woman whose Christian name was "Rita", believing that this Rita might be a witness to what happened between Danvers and Jane Finn on the ship. However, as the list of survivors mostly listed people as Mrs. or Miss, they had to call on the survivors individually to find out their Christian names. Marjorie was one of the people they visited.
