The shocking truth behind a 'mother's death case' that occurred 30 years ago is set to be uncovered in 'Detective's Business Secrets'.

In the episode airing on the 15th, Channel A's 'Detective's Business Secrets' will delve into the mystery surrounding the death of a mother who passed away with significant debts and dozens of insurance policies.

Last week, a client approached the detective agency seeking the truth behind her deceased mother's death. Investigations revealed that the mother had accumulated approximately 123 million KRW in debt, including a 70 million KRW loan. Furthermore, she owned three apartments in addition to the villa she resided in. The suspicion intensified with the discovery of 32 insurance contracts signed over the past decade, 20 of which were death benefit policies.

The client questioned how her mother, who suffered from a mental illness, could have possibly managed all these contracts alone. During the investigation, suspicious circumstances emerged: the mother's place of death was a secluded mudflat, her house door was found open, and her mobile phone was left behind. A neighbor even voiced suspicions of foul play, adding to the tension.

This week, the detectives will visit the management offices of the three apartments, a loan company, and insurance agents to piece together the mother's life. During their inquiries, everyone interviewed consistently mentioned the presence of 'a man' by the mother's side. A former colleague delivered a shocking testimony, stating, "I don't think she died alone." He further revealed, "That man repeatedly demanded money, and eventually, she took out a loan against her house to lend it to him," foreshadowing a major revelation.

The identity of this mysterious man, the focus of all witness accounts and testimonies, will be unveiled during the broadcast.

Meanwhile, comedian Hong Ye-seul will join as a special detective for this episode. She shared humorous anecdotes about her 9-year marriage to a non-celebrity husband and the public's misconception of her comedy sketches with comedian Im Woo-il as reality. 'Detective's Business Secrets' airs on Monday, December 15th, at 9:30 PM KST.

Netizens are buzzing with anticipation about the identity of 'that man.' Comments like 'I'm so curious about who the real culprit is' and 'I expect a shocking twist' are flooding in, raising expectations for the upcoming broadcast.
