A few people gather on Friday the 13th at the Travers mansion, in New York, for the reading of Josiah's will. Which is a wall chart rendered in the form of a rebus(a part word, part drawing puzzle)
that almost defies solution. Instead of designing an heir, it offers the estate to anyone who
can solve the will. The lights keep going out and people keep getting murdered. The audience will have
a ball trying to untangle faster that the hapless characters. By the final act, revelations
are exploding as surprise piles upon surprise and gasps alternate with howls of laughter.
