Suspense's "One Hundred in the Dark" was adapted from a short story by Owen M. Johnson (1878-1952). The original text can be found online in a collection of Johnson's short stories called Murder in Any Degree (1907), which is available at ManyBooks.net. It is also available in the 1918 collection Modern Short Stories: A Book for High Schools, which is available online through the Internet Archive and Google Books. More recently, "One Hundred in the Dark" was published in the 2007 book Uncertain Endings: The World's Greatest Unsolved Mystery Stories.
Suspense made only minor changes in their adaptation and took something of a risk in presenting this story because it does not have the traditional twist ending. This is a sophisticated episode, one that may require pondering.
The episode opens at the fashionable Writers and Artists Club in New York, where a group of gentlemen have just settled in for their after-dinner drinks. They are discussing the evolution of stories and how the basics of human relations are played out and re-interpreted in an endless number of ways. In that regard, thousands of stories are generated from just a few possible scenarios.
Then they pause, while their drinks are being poured.
On they go, but now, one member of the group disagrees. He brings up a conflicting example, a detective story. The others then debate "curiosity" and "intellectual vanity" as the true motivating factors behind detective fiction.
As their discussion continues, one of them brings up the story of the "rare coin and the visitor at club." That leads to the similar story of Rita Kildair, a hostess who had her sapphire ring stolen from one of her guests and the clever way in which she got it back...
