Achilleus isn’t even in charge of the Holloway people. A black boy called Blue is their leader. Blue didn’t seem to mind that Achilleus was ordering people around. So we carried on. Nobody was very happy, but nobody would risk saying anything because, to be fair, it’s not just me; they are all scared of Achilleus, even Einstein I think. Although he tries to pretend he isn’t. The only one who isn’t scared of him is Paddy, and he is all red-faced and sweating, puffing and panting along.

Achilleus has other tough boys around him from Holloway, including another ugly one called Big Mick. Who is not only ugly but also big. I suppose that’s how he got his name. It’s not a clever one like Little John. I will not be rude about Mick, because he is a very good fighter and also when I got a bit tired and said so he carried me for a bit, sort of like he was joking, but it was nice. Mick is not so scary as Achilleus. My favourite one is Ollie, though. He rescued me from a fearsome sicko on the night of the World Book Day attack. Ollie is not scary, he is quite friendly, but quite quiet. I think he is the cleverest of them. He was talking to Einstein for a long time. I thought that if there was trouble Ollie would be sure to look after me. I was not so sure about Achilleus.

My friends from the museum started to grumble and mutter about the new children, but I thought it would be another matter if we ever did meet any sickos. Which we did. But I will come to that in a minute. We carried on like that for roughly about another hour, maybe more, and everyone was cheering up because we were going faster, and the road was good and wide and safe all the way. It used to be the main road west out of London, so it is wide. We went quite easily and were not too fearful of attack. It was mostly raised up or had railings on the sides so there was no danger of sickos coming after us.
