An unpublished collection of short stories by the groundbreaking author Dashiell Hammett, often named as the originator of hardboiled noir fiction, has been discovered in Austin, Texas. Hammett, best-known for the novels The Maltese Falcon, The Thin Man and Red Harvest died in 1961.

The fifteen short stories were found by The Strand magazine editor, Andrew Gulli, at the University of Texas, Harry Ransom Center literary archives. Gulli plans to publish one of the stories in his crime fiction magazine later this month and eventually publish all fifteen in a book.

It’s not yet known why these stories were in the archive, exactly when then were written or if Hammett had planned to publish them at all.
