Researchers have found a previously unseen play written by Pulitzer Prize-winning novelist Edith Wharton, The Guardian reports. The three-act play is titled The Shadow of a Doubt and dates back to 1901.

The Shadow of a Doubt was unearthed among a bunch of papers in an archive in Austin, Texas. Researchers established that the piece was set to be produced at the turn of the century but was eventually postponed.

The play centers on a character named Kate Derwent, a former nurse married to a gentleman. According to The Guardian, the drama takes a dark turn with themes of deception and extortion.

Wharton was a Pulitzer Prize-winning American novelist (her novel The Age of Innocence won the Pulitzer Prize in 1921), short story writer, and designer, who was also nominated for the Nobel Prize in Literature in 1927, 1928, and 1930. She adapted two of her novels, The House of Mirth and Age of Innocence, into plays. Wharton passed away in 1937 at age 75.
