Katherine Moennig will show up on an episode of Dexter this fall.
The cousin of Gwyneth Paltrow - best known for her long-running role on The L Word and most recently seen on Three Rivers - will appear on one episode as a tattoo artist. As initially reported by TV Guide, she'll get embroiled in the serial killer's world... somehow.
In other Dexter casting news, Peter Weller, Johnny Lee Miller, April Lee Hernandez, Shawn Hatosy and Julia Stiles will all recur on season five.
It premieres on September 26.
