chunk: Lowenstein warns Ned that someone kept calling his hotel room on the night of the murder but never got an answer, thereby weakening his alibi. Lewis tells Ned that a woman came to him for another incendiary device, and he showed her how to booby trap a door. Matty calls Ned to tell him the glasses are in the boathouse on the Walker estate. Ned goes to the boathouse late at night and sees a long twisted wire attached to the door. When Matty shows up, Ned confronts her at gunpoint and tells her to get the glasses. Matty walks toward the boathouse and disappears from view; the boathouse explodes. Grace finds a body that is identified as Matty Walker (nĂŠe Tyler) through dental records.
