next moment there they were in the cave, and stepped out of the carriage on the exact spot where Dickie had set out the moon-seeds and Tinkler and the white seal.
The swan carriage went back up the cave with a swish and rustle of wings, and the children went down the hill as quickly as they could—which was not very quickly because of Dickie's poor lame foot. The boy who had killed a Cromwell's man with his little sword had not been lame.
Arrived in the courtyard, Dickie proudly led the way and stooped to examine the stones near the ruined arch that had been the chapel door. Alas! there was not a sign of the inscription which Dickie had scratched on the stone when the Roundheads were battering at the gates of Arden Castle.
Then Edred said, "Aha!" in a tone of triumph.
"I took notice, too," he explained. "It's the fifth stone from the chapel door under the little window with the Arden arms carved over it. There's no other window with that over it. I'll get the cold chisel."
He got it, and when he came back Dickie was on his knees by the wall, and he had dug with his hands and uncovered the stone where he had scratched with the nails. And there was the mark—19. R.D. 08. Only the nail had slipped once or twice while he was doing the 9, so that it looked much more like a five—15. R.D. 08.
"There," he said, "that's what I scratched!"
