Dexter, a television show on Showtime, is headed for a new season. The new season will begin September 27, 2009. Joining the cast of the show for season four is veteran actor John Lithgow. Lithgow gained celebrity fame as Doctor Dick Solomon on the NBC sitcom 3rd Rock from the Sun. Lithgow will play Walter Simmons, a character who is living a double life as America’s most prolific and deadly serial killers.

The show Dexter isn’t your normal television police/detective show. Why? The main character, Dexter Morgan, is a blood spatter analyst for the Miami Metro Police Department. But what most people in the show don’t know is that Dexter is a covert serial killer on the side. The show is based on the novels written by Jeff Lindsay.

Each episode Dexter will track down a criminal that has been a detriment to society, capture them, and then torture them until they die. He will then dispose of the body in trash bags in bodies of water in the area. Dexter is not a show for the faint of heart or someone easily sickened by the sight of blood or other violent pictures. The amount of violence on the show is limited but once Dexter catches a criminal there will be one or two scenes involving nothing but violence.

Dexter typically targets criminals who are murderers, rapists, or other criminals that physically abuse other people or animals. Dexter is a highly addictive show because of the story lines present and what can be included in the show since it is on premium pay television.
