If money is the root of all evil, there are many motives for the murder of Lady Tressilian. Agatha Christie's Towards Zero is a classic whodunnit, mixing mystery with murder. Several guests have been invited for the weekend. Tensions between a few of them become deadly and a murder is committed with all the evidence pointing to one person. Since this is Christie, you know it's got to be a red herring. The true murderer is revealed in a shocking twist ending. Gregory Boyd and John Tyson direct this production, which is part of the Alley's "ExxonMobil Summer Chills" series.
