'Lost' Shakespeare Play Published Double Falsehood is no hoax, experts say By Rob Quinn, Newser Staff Posted Mar 16, 2010 2:54 AM CDT 6 comments Comments English playwright and poet William Shakespeare (1564 - 1616), circa 1600. (Getty Images) (Newser) – A Shakespeare play dismissed as a hoax for nearly 300 years has now been accepted as the real thing. Double Falsehood, now under the name of writer Lewis Theobal, was—as its author always claimed—based on William Shakespeare's long-lost script for Cardenio, scholars say. Shakespeare publisher Arden has now published the play under the Bard's name and made it available in a fully annotated form for the first time in 250 years. "I think Shakespeare's hand can be discerned in Act One, Act Two and probably the first two scenes in Act Three of the play," a Shakespeare expert told the BBC, calling it a "flawed" work due to Theobald's tinkering with the Shakespeare script. The romantic tragi-comedy, based on a section of Don Quixote, will be performed by the Royal Shakespeare Company next summer.
