For the first time in many moons, I’m completely stumped. If you haven’t watched the last episode, here’s the quick lowdown.

The veterinarian YeBun convinces the detective Jang Yeol (JY) that they’re wrong to trust the farmer KwangShik. She suspects that KwangShik is the killer because a) he acted paranoid when she tried to “read” his girlfriend’s memories, as if he was hiding something, and b) he was the one who sent them all looking for a third person with psychic abilities.

Her theory proves wrong, however, when KwangShik is also stabbed to death by the serial killer. Unknown to YeBun and JY, he had gone to office of the former (now deceased) Assemblyman Cha on the pretext of delivering milk when he really wanted to check on the light switch. I think he had a hunch that the killer had “night vision” or could see in the dark.

On his way back to the farm, he’s ambushed by the killer. Despite getting stabbed, he manages to reach YeBun’s clinic and utters one word before he dies. His clue for her is “black.”

Meanwhile, JY encounters the serial murderer, dressed in a raincoat and holding a bloody knife. He chases after him and almost catches him. But the killer slices his arm and escapes.

Following his gut instincts, JY runs to SunWoo’s house and finds him conveniently taking out the trash. He dumps the contents of the trash bag in hopes of finding the bloody knife and/or the wet raincoat. Ha! That would have been too easy.

Instead, he spots the blood, still wet, on SunWoo’s sleeve. The poor guy has no idea how it got there.

With KwangShik’s dead, JY’s back to suspecting Sunwoo but he can’t convince YeBun to stay away from Sunwoo. She’s certain that he can’t be the murderer because a) he’s a decent man and b) she “read” nothing criminal in his memories. Unfortunately for her, her curiosity gets the better of her and she investigates Sunwoo’s toolbox while he’s away with the Shaman. Inside the box, she discovers the bloody knife and concludes that Sunwoo is the killer. She runs away but Sunwoo spots her and chases after her.

It doesn’t cross her mind that if Sunwoo is the killer then a) he should have wiped off the blood to make it look like any ordinary knife, and b) he wouldn’t have wrapped the handle in plastic. To me, Sunwoo found the knife and was keeping it as evidence to hand over to YeBun who would, in turn, give to Detective JY at a more convenient time. He has no intentions to stab her.

But because YeBun assumes the worst about him, she flees from him, and runs straight into the serial killer. Sunwoo dies while protecting her.

So, with KwangShik and Sunwoo out, who’s left as suspect?

Let me see now:

There’s JY’s colleague, the junior detective DeokHee. He certainly looked suspicious when he didn’t want YeBun to touch his behind. But he was nowhere near the crime scenes, when the crimes actually occurred. Nope.

There’s Mr. Kang, the assistant of the dead Assemblyman Cha. He was in the office when KwangShik suddenly showed up to “deliver” milk. However, when the third victim, the coffee shop worker, was killed in the cornfields, he was at Assemblyman Cha’s side at the campaign room. Nope.

My money is on the Shaman Mr. Park.
