Trouble is afoot, and Mom is on the case! Chief Investigator Dave is at the first night of the local amateur theatre's production of Macbeth when the curtain is brought down abruptly on a real-life murder. "The show must go on" and does, but the killings do not end, and there is more drama offstage than on for the doomed production before Dave--and (sshh!) Mom--arrive at the bottom of it all.
