Channel A's 'Detectives' Trade Secrets' covers the theft of a luxury watch worth tens of millions of won in a provincial new town, and the stories of the people entangled in it.

【A Watch Worth Tens of Millions of Won Stolen — the Client Is a 'Husband'】

The broadcast begins with a husband entrusting the detective team with the case of the stolen luxury watch. He said that although he was advised to report it to the police, his wife was the most suspicious party, so he hesitated to file a report.

The husband explained that a year ago, he voluntarily requested a transfer to a factory in a provincial new town in order to be promoted to an executive position. His family wanted to stay in Seoul, but he persuaded them to move with him. He said his wife, who had to adjust to an unfamiliar environment, gradually struggled and suffered from depression.

He also expressed his sense of injustice, saying, 'As punishment for having a wife 10 years younger, I supported everything without shortage — family living expenses, our child's private academy fees, and even my mother-in-law's allowance.'

Then, a change came over his wife. She began socializing with mothers from Seoul, went out more often, and appeared brighter.

The wife claimed her mother had injured her back and requested an additional 1 million won in caregiving fees each month, and the husband increased the amount he sent to his mother-in-law accordingly. However, through his brother-in-law, he learned that his mother-in-law had never been injured, exposing his wife's lies.

Then the husband discovered that the luxury watch he treasured had been replaced with a fake of the same model, and he became convinced that this was his wife's premeditated act.

The husband claimed, 'It wasn't enough for my wife to skim off 1 million won every month under the pretext of caregiving fees for my mother-in-law — she even stole a watch worth more than 20 million won.' When the full story of the case was revealed, Kim Poong said, 'She's given up on being human.'
