Duprey had been set for a long run in the serial with her character being due to marry on-screen love interest, Andy McDonald. However, in late 1993, just as the wedding scenes were about to be recorded by programme maker, Granada TV, Duprey suffered a breakdown and was sent home on leave. After it soon became apparent that she would not be well enough to return to the programme, a storywriter's conference was quickly convened and scripts redrafted. In the programme, viewers saw the engagement between the characters of Andy McDonald and Amy Nelson being hurriedly 'broken off' with another actress being used in the final scenes to play the part of Nelson. Thereafter, Duprey withdrew from the limelight altogether, relocating back to her native Merseyside, and became increasingly reclusive. In 2000 she was found dead in a converted 1930s detached house in Mossley Hill near Liverpool University from a drug overdose. It is believed that her body had lain undiscovered for days. She became more and more solitary and in the end became a virtual recluse. She left one daughter, Marcelle (b. 1976).
