Summary: Actress Jane Helier tells a story of a mysterious burglary at a bungalow in the town where she is acting in a play, involving a woman impersonating her and an unfortunate young playwright. Miss Marple, professing to be baffled, privately hints at a different story.

Most readers are familiar with Agatha Christie's full-length mysteries. This is a delightful short story originally part of an anthology titled Thirteen Problems first published in 1932, and now available in e-book form as a stand-alone short story.

Jane Helier, an actress, is with a party of friends including Miss Marple, and turns the conversation to a mysterious event that happened to a "friend" of hers, who is quickly found out to be Jane herself. She was in a town by a river ("Riverbury") as part of a play company when called upon by the police to confront a young man arrested for burglary. The story gets more interesting when the young man, a playwright, claims he was summoned to a bungalow, the site of the burglary, by Miss Helier. Of course, when he sees Miss Helier, he realizes the other woman was not her. He had called at the bungalow, was introduced by the maid to "Miss Helier," had a drink, and woke by the side of the road, only to be arrested for burglary. It seems that a case of jewels owned by the mistress of a wealthy city man has been stolen while the house was empty. The mistress was an actress, herself married.

By then it is obvious that the young playwright, Leslie Faulkener, was innocent of the crime. But who stole the jewels? The actress, the maid? The party weights all the angles of the story, and at the end, even Miss Marple professes to be mystified as to the solution, and their ire is further aroused when Jane Helier herself offers no resolution.

As the party is breaking up Miss Marple whispers in Jane's ear, leaving her startled. Did Miss Marple know more than she let on, that not all was as it seemed? And what did she mean when she said, "What I do realize is that women must stick together--one should, in an emergency, stand by one's own sex. I think that's the moral of the story Miss Helier has told us"? What did Miss Marple whisper in her ear?

The one question, which mystifies Miss Helier herself, also mystified me and that is how did Miss Marple know? The resolution of the mystery hinges on information Miss Helier had not told anyone, including Miss Marple, introducing new characters not known to us. How did she know? Was it the vagueness at points in the story? The fact that Miss Helier herself does not know the ending?

In this case, one has only to read twenty-one pages to discover what is going on. But the story demonstrates Christie's art--to draw one into a crime puzzle--in this case one without a murder, and finish it with a surprise ( )
