The best season of Dexter came with the case of the Trinity Killer, dubbed because it seemed as if his killing came in groups of three. It was the most psychological villain Dexter ever faced and left a massive hole in Dex’s life after Trinity killed Dexter’s wife Rita, which did not learn about until after Trinity wound up on Dexter’s table. John Lithgow earned himself an Emmy Award for his appearance.
