John Buchan’s The 39 Steps, the quintessential ripping yarn, is being sent up in what has become a theatrical classic.  The play calls for the entire story to be performed with a cast of only four.  One actor plays the hero, Richard Hannay, an actress plays the three women with whom he has romantic entanglements, and two other actors play everyone else in the show: heroes, villains, men, women and children; in all there are 150 characters! The performance goes at breakneck speed and is played for laughs all the way.  No wonder this wickedly funny adaptation won the Olivier Award for Best Comedy in 2007.
