When police forced their way into the Hong Kong flat of bar hostess Suzy Kim Ock-pun on January 20, 1987, and found her decaying corpse stuffed under a bed, they were unravelling a tale of international espionage and deceit.
Kim - or Suzy as she was to become known - had been strangled with a belt, and when detectives found her, had a pillow case slipped over her head.
Two weeks earlier her husband, Yoon Tae-shik, 43, had reported her missing to the Hong Kong police before he left the territory for Singapore.
Events that followed caused a sensation in South Korea and eventually led the Hong Kong detectives investigating the killing to doubt the credibility of Yoon's claims of a North Korean kidnap plot.
On January 7, 1987 - almost two weeks before Kim's body was discovered - a tearful Yoon appeared on South Korean TV in a news conference apparently arranged by Seoul's spy organisation, the Korean Central Intelligence Agency (KCIA).
Yoon's story was that a few days earlier two men had turned up at the couple's flat in Knutsford Terrace, Tsim Sha Tsui, to see his 34-year-old wife. They had told him to make himself scarce and when he returned, she was gone.
