In "Nothing Uncovered" episode 4, Kim Ha Neul and Yeon Woo Jin see a much clearer picture of the culprit's real identity after a series of investigations.

Here's what went down in the brand new episode of the dama.

Seo Jung Won's Suspicions Grow Stronger

After being questioned as a witness, Seo Jung Won (Kim Ha Neul) returns to the hotel to look for more evidence to support her suspicions.

She examines the photos that were taken from Cha Eun Sae's (Han Ji Eun) murder scene. However, the necklace that she also has isn't visible in the area even when zoomed in.

Seo Jung Won becomes more convinced that someone left the necklace behind after her husband, Seol Woo Jae (Jang Seung Jo), had left the scene on the day of the murder.

Meanwhile, Seol Woo Jae heads to the crime scene, and stops by the neuropsychiatry department where Seo Jung Won goes to meet Yoo Yoon Young (Han Chae Ah).

Seol Woo Jae Hides Huge Secret

Seol Woo Jae asks Seo Jung Won's doctor to help him, raising curiosity about the real score between the two. On the other hand, Seo Jung Won visits her father-in-law.

Seol Pan Ho (Jung Woong In) plans to abolish Seo Jung Won's news program due to the negative impact that she has on the Seol family's image.

Seo Jung Won is determined to stop the abolition, even if she kneels down in front of her father-in-law. Unfortunately, the chairman doesn't budge.

Did Seol Woo Jae Murder Cha Eun Sae?

At the newsroom, Seo Jung Won publicly apologizes, revealing that she trusts and supports her husband with no questions. This angers Kim Tae Heon (Yeon Woo Jin).

The detective then immediately meets up with Seo Jung Won to clear things out. He stops in his tracks when he discovers a photo of Cha Eun Sae's murder on Seo Jung Won's laptop.

Yeon Woo Jin also discovers a wine-colored coat that is identical to the one worn by an unknown woman in the CCTV footage in the hotel on the day of Cha Eun Sae's murder.

Seo Jung Won is left dazed and confused. To find answers, she listens to the tape recorder that she installed without Seol Woo Jae's knowledge before she leaves their newlywed home.

At the end of the episode, Seo Jung Won discovers a wine-colored coat identical to what she owns which is worn by someone who's consulting with Yoo Yoon Young, raising suspicions.
