Jane (The Unbreakable Alibi)

In the short story The Unbreakable Alibi, Jane is a friend of Tuppence Beresford. She lends Tommy and Tuppence some photos they can use in their enquiries about the wearabouts of Una Drake. Tuppence said that they needed to have photographs of four or five other girls besides the photo of Una. That was the way it was always done in books. When checking if a person was at a certain place, one showed four or five photos to the witness and asked the witness to pick out the person he saw. The Beresfords first tried getting photos of girls from a photographer but were rebuffed. Fortunately Jane was able to help them by providing photos of her friends.

Jane is not featured in LWT's 1983 adaptation of the story (Episode 7 of Agatha Christie's Partners in Crime). There, Tuppence merely shows the picture of Una Drake to witnesses and asks if they remember her.
