After a while, Thwaites broke the silence. ‘She must have got one heck of a shock,’ he said. He paused. We all looked at him, wondering what wisdom the great medical authority was going to come out with next.
‘After all,’ he went on, ‘to catch hold of a dead mouse when you’re expecting to catch hold of a Gobstopper must be a pretty frightening experience. Don’t you agree?’
Nobody answered him.
‘Well now,’ Thwaites went on, ‘when an old person like Mrs Pratchett suddenly gets a very big shock, I suppose you know what happens next?’
‘What?’ we said. ‘What happens?’
‘You ask my father,’ Thwaites said. ‘He’ll tell you.’
‘You tell us,’ we said.
‘It gives her a heart attack,’ Thwaites announced. ‘Her heart stops beating and she’s dead in five seconds.’
For a moment or two my own heart stopped beating. Thwaites pointed a finger at me and said darkly, ‘I’m afraid you’ve killed her.’
‘Me?’ I cried. ‘Why just me?’
‘It was your idea,’ he said. ‘And what’s more, you put the mouse in.’
All of a sudden, I was a murderer.
At exactly that point, we heard the school bell ringing in the distance and we had to gallop the rest of the way so as not to be late for prayers.
Prayers were held in the Assembly Hall. We all perched in rows on wooden benches while the teachers sat up on the platform in armchairs, facing us. The five of us scrambled into our places just as the Headmaster marched in, followed by the rest of the staff.
The Headmaster is the only teacher at Llandaff Cathedral School that I can remember, and for a reason you will soon discover, I can remember him very clearly indeed. His name was Mr Coombes and I have a picture in my mind of a giant of a man with a face like a ham and a mass of rusty-coloured hair that sprouted in a tangle all over the top of his head. All grown-ups appear as giants to small children. But Headmasters (and policemen) are the biggest giants of all and acquire a marvellously exaggerated stature. It is possible that Mr Coombes was a perfectly normal being, but in my memory he was a giant, a tweed-suited giant who always wore a black gown over his tweeds and a waistcoat under his jacket.
Mr Coombes now proceeded to mumble through the same old prayers we had every day, but this morning, when the last amen had been spoken, he did not turn and lead his group rapidly out of the Hall as usual. He remained standing before us, and it was clear he had an announcement to make.
‘The whole school is to go out and line up around the playground immediately,’ he said. ‘Leave your books behind. And no talking.’
Mr Coombes was looking grim. His hammy pink face had taken on that dangerous scowl which only appeared when he was extremely cross and somebody was for the high-jump. I sat there small and frightened among the rows and rows of other boys, and to me at that moment the Headmaster, with his black gown draped over his shoulders, was like a judge at a murder trial.
‘He’s after the killer,’ Thwaites whispered to me.
I began to shiver.
‘I’ll bet the police are here already,’ Thwaites went on. ‘And the Black Maria’s waiting outside.’
As we made our way out to the playground, my whole stomach began to feel as though it was slowly filling up with swirling water. I am only eight years old, I told myself. No little boy of eight has ever murdered anyone. It’s not possible.
Out in the playground on this warm cloudy September morning, the Deputy Headmaster was shouting, ‘Line up in forms! Sixth Form over there! Fifth Form next to them! Spread out! Spread out! Get on with it! Stop talking all of you!’
Thwaites and I and my other three friends were in the Second Form, the lowest but one, and we lined up against the red-brick wall of the playground shoulder to shoulder. I can remember that when every boy in the school was in his place, the line stretched right round the four sides of the playground – about one hundred small boys altogether, aged between six and twelve, all of us wearing identical grey shorts and grey blazers and grey stockings and black shoes.
‘Stop that talking!’ shouted the Deputy Head. ‘I want absolute silence!’
But why for heaven’t sake were we in the playground at all? I wondered. And why were we lined up like this? It had never happened before.
I half-expected to see two policemen come bounding out of the school to grab me by the arms and put handcuffs on my wrists.
A single door led out from the school on to the playground. Suddenly it swung open and through it, like the angel of death, strode Mr Coombes, huge and bulky in his tweed suit and black gown, and beside him, believe it or not, right beside him trotted the tiny figure of Mrs Pratchett herself!
