In 1946, Potter passed the eleven-plus and attended Bell's Grammar School at Coleford. Most of his secondary education however, was in London, and it was in a street near Hammersmith Broadway that the ten-year-old Potter was sexually abused by his uncle, an experience he would later allude to many times in his writing. During his speech at the 1993 James MacTaggart Memorial Lecture, Potter referred to this event when explaining his decision to switch from newspaper journalism to screenwriting: "Different words had to be found, with different functions. But why? Why, why, why; the same desperately repeated question I asked myself without any sort of an answer, or any ability to tell my mother or my father, when at the age of ten, between V.E. Day and V.J. Day, I was trapped by an adult's sexual appetite and abused out of innocence." His family returned to the Forest of Dean in 1952, having first left it in 1945, but Potter remained in London.
