A man is done in by his wife, but he's not done yet. Evidently his ghost is unquiet.

A composer is up against it, and Sally's somehow connected to him.

After receiving the Cop of The Year award, Sgt. Enright is accused of the murder of his ex-wife--and the case against him seems air-tight.

The mob abducts Mac and replaces him with a surgically-altered lookalike, to liquidate a squealer in a tightly-guarded hospital.

Sally's next on a maniac's agenda; a psychiatrist assists.

Sally is kidnapped at an art museum. The ransom: a priceless painting owned by Spain that they are unwilling to relinquish. Mac's only clue takes him back to the day he proposed to Sally.
