No reader who understands justice and the real rightness of things, and who is to blame for what, will ever think it could have been Oswald’s fault that the two other boys got along down by rolling over and over each other, and bursting the door at the bottom of the stairs open by their revolving bodies. And I should like to know whose fault it was that Mrs Pettigrew was just on the other side of that door at that very minute? The door burst open, and the impetuous bodies of Noel and Denny rolled out of it into Mrs Pettigrew, and upset her and the tea-tray. Both revolving boys were soaked with tea and milk, and there were one or two cups and things smashed. Mrs Pettigrew was knocked over, but none of her bones were broken. Noel and Denny were going to be sent to bed, but Oswald said it was all his fault. He really did this to give the others a chance of doing a refined golden deed by speaking the truth and saying it was not his fault. But you cannot really count on anyone. They did not say anything, but only rubbed the lumps on their late-revolving heads. So it was bed for Oswald, and he felt the injustice hard.
But he sat up in bed and read The Last of the Mohicans, and then he began to think. When Oswald really thinks he almost always thinks of something. He thought of something now, and it was miles better than the idea we had decided on in the secret staircase, of advertising in the Kentish Mercury and saying if Albert’s uncle’s long-lost grandmother would call at the Moat House she might hear of something much to her advantage.
What Oswald thought of was that if we went to Hazelbridge and asked Mr B. Munn, Grocer, that drove us home in the cart with the horse that liked the wrong end of the whip best, he would know who the lady was in the red hat and red wheels that paid him to drive us home that Canterbury night. He must have been paid, of course, for even grocers are not generous enough to drive perfect strangers, and five of them too, about the country for nothing. Thus we may learn that even unjustness and sending the wrong people to bed may bear useful fruit, which ought to be a great comfort to everyone when they are unfairly treated. Only it most likely won’t be. For if Oswald’s brothers and sisters had nobly stood by him as he expected, he would not have had the solitary reflections that led to the great scheme for finding the grandmother.
