Jonathan Silverman has a regular role — opposite wife Jennifer Finnigan — on "Salvation" this summer, but he also appears here in the new episode "Smoking Gun," playing a Hollywood producer who is found holding a literal smoking gun while standing near his slain mistress. He maintains his innocence in her death, and Sam (Rachel Bilson) believes him, though Eddie (Eddie Cibrian) thinks the case is open-and-shut. The resulting probe yields lots of surprises, including false identities. Aliyah O’Brien also stars.
