Reverend Lee doesn't realise that his dyslexia is affecting his sermons. His parishioners are at first amused and then shocked by the garbled messages coming from the pulpit. Finally a cure is found. The Vicar must walk backwards for the rest of his life. By the author of The Witches.

From the backcover

"My name is Eel, Robert Eel. I am the new rotsap of Nibbleswicke. Dog help me!"
The Reverend Lee is suffering from a rare and acutely embarrassing condition: Back-to-Front Dyslexia. It affects only his speech, and he doesn't realize he's doing it, but the parishioners of Nibbleswicke are shocked and confused by seemingly outrageous comments.
At last a cure is found and the mild-mannered vicar can resume normal service. Or at least as normal as is possible for a man who must walk backwards to be sure of taking forwards!
A highly comic tale in the best Dahl tradition of craziness, written for the benefit of the Dyslexia Institute.
