On Tuesday 3rd May, 1988, two people were sighted on horses around the area of Powerscourt, County Wicklow, Ireland. One was recognised as Lynda Kavanagh, the other person was not immediately identified, but believed to be Priscilla Clarke, the Kavanaghs live-in nanny. Two days later, Lynda Kavanagh’s body was recovered from the local River Dargle. Priscilla’s body was never recovered and her family were never able to bring closure and finality to her disappearance. She was aged 25 at that time and the mystery of her disappearance has lasted for 36 years.
