“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.
