Someone is killing off the only people who can read the clues to an old murder hidden within Jonathan Aldrich's new play.In a small New Hampshire town, Aldrich, an eccentric, once-famous author, dies and bequeaths his estate to seven individuals, with the condition that they each attend the posthumous opening of Whodunit, an old-fashioned murder mystery.At least, that's what the residents of Harpers Crossing are led to believe.When the executor of the Aldrich estate is murdered, Attorney Matthew Harper, a descendent of the town's founder, is assigned the duty of carrying out the terms of the will. But when he finds that all seven beneficiaries have recently died in suspicious accidents, he begins to suspect that something more sinister than an innocent summer-stock production is involved.And the body count has just begun.
