'Thorne: Scaredy Cat' Exclusive Preview: David Morrissey And Sandra Oh Solve Crimes (VIDEO)

Sandra Oh has some experience with sharp objects thanks to her role on "Grey's Anatomy," but in "Thorne: Scaredy Cat," (airing June 13 at 9 p.m. ET on Encore) she's not the one administering the cuts.

Oh joins David Morrissey (the titular prickly detective) in Wednesday night's conclusion of the chilling miniseries, playing a troubled cop who is battling a serious drug addiction while attempting to hold on to her career. The episode also features "Sherlock Holmes" actor Eddie Marsan, portraying a somewhat more aggressive character than the clueless but well-meaning Lestrade from the Robert Downey Jr. franchise.

In "Scaredy Cat," after the bodies of two female victims are found at the same time -- killed in the exact same way -- Thorne finds himself on the hunt for not one, but two serial killers who seem to be working together, yet killing separately. Thorne starts to unravel a case that twists and turns back through ten years. And when the suspect escapes, he finds himself on a desperate hunt for two killers again -- one who is desperate to stop and one who is terrified of the consequences if he does.

After previewing the series last week, HuffPost TV has two more exclusive clips from the crime drama, which show Marsan and Oh in action in tonight's installment. Check them out and tune in at 9 p.m. ET.

"Thorne: Scaredy Cat" airs Wednesday, June 13 at 9 p.m. ET on Encore.
