Mark Valley Joins CSI Cast; Plays Potential Love Interest For Finlay

The versatile Mark Valley (who, just like Gil Bellows) appears in practically everything I watch is joining another new show.

Valley has signed on for a recurring role on CSI. The actor will play a former detective who now works as a private investigator. When Valley’s partner goes missing, he joins Finlay (Elisabeth Shue) to try and solve the case and while their relationship starts off rocky, it’s clear their is a romantic connection.
