On the 2nd February 1986, nurse and former pageant queen Anita Cobby finished work at Sydney Hospital at 3pm and met friends for dinner in nearby Redfern. She then boarded a train from Central Railway station heading home. Arriving at Blacktown, she would usually ring her father who would pick her up, however on this day she found all the phones out-of-operation and decided to walk the small distance home .

The next day, Anita Cobby failed to arrive at work.

Clare presents this case.

On the 24th October 1997 a dinner party is held in Canberra, Australia. Rumour has it that the young couple hosting this dinner (25-year-old Anu Singh and her 26-year-old boyfriend Joe Cinque) have together chosen to end their lives, and this dinner is to be their unspoken "farewell". Nobody mentions the rumour, and nobody warns Joe.

Laci Peterson, the pregnant 27-year-old wife of Scott Peterson, disappeared from her home of Modesto, California, in December 2002. Scott Peterson became a suspect from the outset. Within days, a woman came forward saying that she was having a romantic relationship with Scott Peterson, and that he had claimed he was a widower preparing to spend his first Christmas alone... several weeks before his wife's actual disappearance.
