AMC's The Killing Gets Help From Mark Moses

Looks like The Killing is getting serious about solving Rosie Larsen’s murder. Desperate, even.

Mark Moses, well-known for playing Paul Young on ABC’s Housewives, is joining the AMC series in Season 2 for a major arc as Lt. Carlson, a new detective at the Seattle police department, according to The Hollywood Reporter.

As TVLine previously reported, Lt. Carlson is described as a clean-cut and well-dressed lawman who keeps tabs on which way the political winds are blowing. He will help investigate Rosie’s death in at least eight episodes.

Moses’ casting on The Killing marks a reunion for the actor and AMC. He memorably played Peggy’s lover and account services head Herman “Duck” Phillips on Mad Men. Recently, he has guested on episodes of Covert Affairs and Criminal Minds.

Season 2 of The Killing will debut in the spring.
