The wife of a businessman who died in a mysterious fall will appear in a documentary in which she will tell how she is still searching for her slice of his missing millions.
Scot Young, 52, died in 2014 after plunging on to railings from a townhouse balcony in London.
The Dundonian and his estranged wife Michelle had been involved in a £400 million divorce battle, the longest in British legal history, before his death.
Michelle, who is the mother of Mr Young’s two children and was eventually awarded £26 million in a settlement, will appear in a BBC documentary on Wednesday.
Investigators have continued to probe Mr Young’s complicated finances in the years following his death.
But they have drawn a blank and funding for the action has ended.
During the divorce proceedings, Mr Young was jailed for six months for refusing to disclose his finances to the courts and pay maintenance to Michelle.
He eventually declared himself bankrupt, which was overseen by London-based accountancy firm Grant Thornton.
Michelle, a former fashion buyer, now lives in a two-bedroom flat in London.
As well as casting doubt on whether she will ever get a penny, one of her key advisers has also questioned Grant Thornton’s involvement in the case.
International asset recovery specialist L. Burke Files, who is based in the US, said: “Scot was meticulous in all his business dealings.
“Where did all the money go? We might never know. But I doubt he lost it. He was very clever.”
In his prime, the tycoon — who was the son of former Dundee United footballer Duncan Young — was said to be worth £800m and counted some of the UK’s most successful businessmen among his friends, including ex-BHS boss Sir Philip Green.
Michelle has also given an interview in which she claims Mr Young didn’t jump to his death but was murdered.
The couple separated in 2006. Three years later, a judge ordered Mr Young to hand over £27,500 a month.
In 2013, his estranged wife said she would settle for £300m, claiming Mr Young was worth “a few billion at least”. But she was eventually awarded £27m.
Mr Young’s death has been likened to a plot from BBC series McMafia, with links to criminal gangs in Russia where he did much of his work. He is believed to have thrown himself on to railings from the fourth-floor window of his girlfriend Noella Reno’s home.
But a 2015 inquest into his death found that there was insufficient evidence to conclude that he took his own life.
A spokesman for Grant Thornton said: “I can confirm that Grant Thornton’s work was both rigorous and thorough in its role as trustee in the bankruptcy of Mr Young.”
n Millionaires’ Ex-Wives Club will be broadcast on BBC Two at 9pm.
