Quadrangle

When Bill Imes arrives at the park one evening to walk his dog, he sees a man and womanwho arrived in separate carsembracing in the parking lot. Bill realizes that hes seen the man before; theyd had a run-in several months back. A few days later, Bill is shocked when he reads in the newspaper that the man has been murdered; he is doubly horrified when a clue leads the police straight to his own apartment door. Slowly but surely, Bill finds himself unwittingly dragged into a twisted tale of love, adultery, and revenge.
