They reached King's Cross at half past ten. Uncle Vernon dumped Harry's trunk onto a cart and wheeled it into the station for him. Harry thought this was strangely kind until Uncle Vernon stopped dead, facing the platforms with a nasty grin on his face.

“Well, there you are, boy. Platform nine — platform ten. Your platform should be somewhere in the middle, but they don't seem to have built it yet, do they?”

He was quite right, of course. There was a big plastic number nine over one platform and a big plastic number ten over the one next to it, and in the middle, nothing at all.

“Have a good term,” said Uncle Vernon with an even nastier smile. He left without another word. Harry turned and saw the Dursleys drive away. All three of them were laughing. Harry's mouth went rather dry. What on earth was he going to do? He was starting to attract a lot of funny looks, because of Hedwig. He'd have to ask someone.

He stopped a passing guard, but didn't dare mention platform nine and three-quarters. The guard had never heard of Hogwarts and when Harry couldn't even tell him what part of the country it was in, he started to get annoyed, as though Harry was being stupid on purpose. Getting desperate, Harry asked for the train that left at eleven o'clock, but the guard said there wasn't one. In the end the guard strode away, muttering about time wasters. Harry was now trying hard not to panic. According to the large clock over the arrivals board, he had ten minutes left to get on the train to Hogwarts and he had no idea how to do it; he was stranded in the middle of a station with a trunk he could hardly lift, a pocket full of wizard money, and a large owl.

Hagrid must have forgotten to tell him something you had to do, like tapping the third brick on the left to get into Diagon Alley. He wondered if he should get out his wand and start tapping the ticket inspector's stand between platforms nine and ten.
