A hit in both New York and London, 39 Steps distills Alfred Hitchcock's 1935 film version of John Buchan's spy novel into a spoof in which an innocent man is dragged into international intrigue. The play takes the whodunit story's stream of characters and man-on-the-run scheme as a comedic dare. Tickets $30.
