But man cannot live on bread alone, and Christie admitted that writing for the same detectives over and over could get boring. Luckily, Christie was prolific as hell, so besides the fifty novels featuring the previous characters mentioned, there are another seventeen that do not mention them at all....though some do feature supporting characters from their adventures. That's under her own name; under the name Mary Westmacott, she published six novels deemed "romantic", though this was a catch-all for "women's lit", books about non-murderous women and their relationships. She wrote a great many plays, too, even adapting her own novels for the stage - and when she did, she did not include her famous detectives.
And then there are the short stories. A great many mysteries, yes, but it was in this medium that she really experimented with genres: ghost stories, adventure yarns, investigations into psychic phenomena. What stands out most, though, is not just the variety, but the bleakness of these stories: suicides, dead children, petty revenge.
Not that she completely abandoned her thrillers, but here she made them more, well, thrilling - less detective stories with clues than regular people confronting murder and madness around them. And for some reason, the most popular among these - for a while, at least - was the short story "Philomel Cottage." It's of that oft-familiar Is My Husband Trying To Kill Me subgenre of thrillers. Here, a woman inherits a butt-load of money, has a whirlwind romance and marriage to a charming man she meets at a party, and only when she is whisked off to a secluded cottage does she begin to realize he may be a Black Widower.
First published in The Grand Magazine in 1924, it was later collected in The Listerdale Mystery (1934, UK only) and The Witness for the Prosecution (1948, US only). But it's real claim to immortality is in a popular stage production, written by and starring Frank Vosper. Popular and well-reviewed on both the West End and Broadway in 1936, the independent Trafalgar Films in turn adapted the production for the screen. In doing so, the filmmakers included some elements of Christie's source material - names, for example - and so were able to credit both the play and short story separately. The title, however, was all Vosper's:
