In June 2006, the death was announced of the pianist Joyce Hatto.
She was heralded as a great lost genius of classical music- a reclusive woman who almost never performed in public, but who in later life had created sublime recordings in private.
A few months later it emerged that those recordings were fake- lifted from other performers and tweaked in the studio - which leaves a question hanging.
In this programme, the biographer Anne Sebba asks 'Who was Joyce Hatto?'
'In the final few years of her life, she released a huge range of CD recordings which swamped the market and were praised to the hilt by a select band of reviewers,' says Anne, 'I remember thinking, Where had this amazing talent been all these years'?
Then, after a pile of glowing obituaries, which told of her four decade battle with cancer, these recordings of the pianist Joyce Hatto were branded as fake - copies of commercial recordings made by other artists, - not by Joyce at all.
In this programme, her husband, William Barrington Coupe, the sound engineer for her recordings, said that he alone was to blame for the deception- acting purely out of love, and replacing passages of his wife's playing with other artists.
But behind the final deception, there is an intriguing story of an incredibly talented pianist marred by ill-health.
