When Agatha Christie's brilliantly plotted courtroom whodunit first opened on Broadway in 1954, the New York Herald Tribune proclaimed that its central mystery is so thrilling "you are apt to find yourself gasping out loud." Audiences for over half a century have delighted in unraveling the mystery of this finely crafted play, and now you too can act as armchair detective when Witness for the Prosecution comes to Rochester's Avon Players Theatre. Christie's tale centers around small-time inventor Leonard Vole, who's been arrested for the murder of the elderly widow Emily French. Vole happens to be French's principal heir, making things look bad for the defense. Then Vole's wife sends shockwaves through the courtroom by testifying as a witness -- for the prosecution! -- and the trial becomes a riveting roller coaster of suspense.
