Isla Forsythe is the ex-wife of Adam Forsythe.
Isla first appears in 2005, to amicably end her marriage to Adam. In November 2006, she lies and gives evidence against Adam's new wife Steph, but she cracks under questioning and admits to the court that she is lying. After Steph and Adam were sentenced, she informed Adam's father-in-law Alan Turner that he committed suicide while in prison.
