Secret of the Coffin- Concluding part aired on May 31
Catherine cries looking at Jack's dead body. She blames CID for his death. Pratap finds a letter in dead body's pocket, which says this is what you get for informing CID special bureau.
At forensic lab Dr. Bharadwaj performs DNA test, dental test on dead body and it matches with Jack's previous records. Then he turns Jack's body to one side and there is a deep wound there. Dr. tells CID team that the body's pancreas and liver is full of water. The conclusion is that this body was kept in a freezer for long time and he died around 1.5 years ago. Now CID team is shocked. Pratap wonders how Jack can die 1.5 years ago then die few days ago and then disappear again? Jasmine says that Jack's death certificate says he dies on 25th May so if this is Jack then who died on 25th?
CID team reaches Catherine's' house and tell her that the guy who died on 25th was not Jack but someone else and her real husband died 1.5 years ago. Peter asks them if they know who killed Jack. They search the house for some clues. They get some medical reports, tapes and photo albums. They take those with them to the bureau.
Dr. Bharadwaj says he will try to match the voice in this tape with the voice in the tape Catherine received on 24th (the one she received in part 1 of the show). He tries some voice modulation machine and finds that both the voices are different. So the guy who disappeared from graveyard is not Jack. But in the second tape they hear airplane landing sound and Tejali says that Catherine's house is near airport. She suspects Catherine. Gargi and Pratap find Vipul with Jack in on of the photos.
CID team goes to Vipul's house. Pratap threatens him to tell the truth. Vipul says he didn't know Jack. Pratap shows the photo. Vipul says that is not Jack but Kiran. He tells them that Kiran and he were friends and one day they saw Jack who looked like Kiran. (I didn't like this twist. Humshakal dramas are so outdated. )
. So they kidnapped Jack and tied him in a godown then Kiran changed himself into Jack and stabbed Jack (that was the deep wound Dr.Bharadwaj found earlier). Kiran changed after becoming rich. He didn't give any money to Vipul as promised. Vipul threatened him but Kiran refused to give him any money. Tejali calls Ajatshatru and tells him that she has brought Catherine to the bureau for interrogation.
CID team asks Catherine to tell the truth. She cries and tells them that she actually married Kiran but thought he was Jack. When Vipul started threatening Kiran he told everything about Jack to her and she agreed to go along with his plan. So Kiran plotted the death drama but Vipul got to know about it somehow and involved CID. So Jack planned the kidnapping and then brought real Jack's dead body so to close the case and then Kiran and Catherine planned to flea the country forever with Jack's money. She says that her husband Kiran is waiting for her at Hotel Queen Palace.
She takes CID team there. But they find another guy in the room. While they are interrogating the guy, Kiran comes in and seeing CID he runs and Catherine runs along with him and CID team after them. Finally Ajatshatru shoots Kiran in the legs and arrest him and Catherine and brings them to the bureau where Kiran agrees to the crime.
