Mr Dursley sat frozen in his armchair. Shooting stars all over Britain? Owls flying by daylight? Mysterious people in cloaks all over the place?

When Mr and Mrs Dursley woke up on the dull, grey Tuesday our story starts, there was nothing about the cloudy sky outside to suggest that strange and mysterious things would soon be hap pening all over the country.

The Dursleys had everything they wanted, but they also had a secret, and their greatest fear was that somebody would discover it.

And finally, bird-watchers everywhere have reported that the nation’s owls have been behaving very unusually today. #harrypotter #Hogwarts

It was on the corner of the street that he noticed the first sign of something peculiar – a cat reading a map. #harrypotter #Hogwarts

Mr and Mrs Dursley, of number four, Privet Drive, were proud to say that they were perfectly normal, thank you very much. #harrypotter #Hogwarts
