Earlier this year, Yale University Press published "Exorcism," Eugene O'Neill's "lost play."

It had been believed that all copies of the work had been destroyed, but a researcher discovered a remaining version of this one-act that O'Neill based on his own suicide attempt.

This year's O'Neill Celebration will focus on "Exorcism," which is being described as a prequel to "Long Day's Journey into Night." Celebration highlights are a reading of the play and then a panel discussion of it and its foreshadowing of "Long Day's Journey."

The O'Neill Celebration events - all free, all held at the Monte Cristo Cottage, 325 Pequot Ave., New London - are:
