“This case grows upon me, Watson,” said he. “There are decidedly some points of interest in connection with it. In this early stage, I want you to realize those geographical features which may have a good deal to do with our investigation.
“Look at this map. This dark square is the Priory School. I’ll put a pin in it. Now, this line is the main road. You see that it runs east and west past the school, and you see also that there is no side road for a mile either way. If these two folk passed away by road, it was this road.”
“Exactly.”
By a singular and happy chance, we are able to some extent to check what passed along this road during the night in question. At this point, where my pipe is now resting, a county constable was on duty from twelve to six. It is, as you perceive, the first cross-road on the east side. This man declares that he was not absent from his post for an instant, and he is positive that neither boy nor man could have gone that way unseen. I have spoken with this policeman to-night, and he appears to me to be a perfectly reliable person. That blocks this end. We have now to deal with the other. There is an inn here, the Red Bull, the landlady of which was ill. She had sent to Mackleton for a doctor, but he did not arrive until morning, being absent at another case. The people at the inn were alert all night, awaiting his coming, and one or other of them seems to have continually had an eye upon the road. They declare that no one passed. If their evidence is good, then we are fortunate enough to be able to block the west, and also to be able to say that the fugitives did not use the road at all.”
“But the bicycle?” I objected.
Quite so. We will come to the bicycle presently. To continue our reasoning: if these people did not go by the road, they must have traversed the country to the north of the house or to the south of the house. That is certain. Let us weigh the one against the other. On the south of the house is, as you perceive, a large district of arable land, cut up into small fields, with stone walls between them. There, I admit that a bicycle is impossible. We can dismiss the idea. We turn to the country on the north. Here there lies a grove of trees, marked as the “Ragged Shaw,” and on the farther side stretches a great rolling moor, Lower Gill Moor, extending for ten miles and sloping gradually upward. Here, at one side of this wilderness, is Holdernesse Hall, ten miles by road, but only six across the moor. It is a peculiarly desolate plain. A few moor farmers have small holdings, where they rear sheep and cattle. Except these, the plover and the curlew are the only inhabitants until you come to the Chesterfield high road. There is a church there, you see, a few cottages, and an inn. Beyond that the hills become precipitous. Surely it is here to the north that our quest must lie.”
“But the bicycle?” I persisted.
“Well, well!” said Holmes, impatiently. “A good cyclist does not need a high road. The moor is intersected with paths, and the moon was at the full. Halloa! what is this?”
There was an agitated knock at the door, and an instant afterwards Dr. Huxtable was in the room. In his hand he held a blue cricket-cap with a white chevron on the peak.
“At last we have a clue!” he cried. Thank heaven! at last we are on the dear boy’s track! It is his cap.”
“Where was it found?”
In the van of the gipsies who camped on the moor. They left on Tuesday. To-day the police traced them down and examined their caravan. This was found.”
“How do they account for it?”
They shuffled and lied — said that they found it on the moor on Tuesday morning. They know where he is, the rascals! Thank goodness, they are all safe under lock and key. Either the fear of the law or the Duke’s purse will certainly get out of them all that they know.”
