“By all means walk across to the line, Mr Holmes, though I cannot see how it will help you. If you go out through the back of the building, the playing field lies before you. Your route is straight ahead. The railway is clearly visible on its embankment. It should not take you half an hour. On your return, we shall have tea before your talk with Riley.”
The expression on my friend’s face indicated that, though nothing would prevent him from talking to Patrick Riley, wild horses would not drag him to take tea with the headmaster.
Reginald Winter watched us walk away down the corridor and stood there until we had passed the glass door which separated his quarters from the rest of the main school. As he disappeared into his study, Holmes held up his finger, a quiet gesture of self-reproach.
“My hat,” he said absent-mindedly.
He went back to the hall-stand, with its mirrors, hooks and racks. Taking down his travelling-cap, he adjusted it in the glass. His eyes made a careful survey of boots and umbrellas, which were presumably the headmaster’s outdoor wear, almost as if he had thought of borrowing some of it.
I was uneasy in case Winter should reappear from the study and catch us examining his effects. But Holmes had not quite done. As I have mentioned, the walls of the corridor were hung with group photographs of the pupils. They were all at their lessons just now. I had noticed the photographs were “Drake Term,” “Anson Term,” or “Nelson Term,” each intake of boys christened after a hero of the fleet. To my relief, Holmes presently turned away from this display and walked towards me.
“And now, Watson,” he said briskly, “let us make the best of the time that our reluctant host has unwisely allowed us.

“Hardly the companion I should choose for a walking tour or a reading party,” I said, as we crossed the playing field towards a gate in the hedge and moved out of earshot of the buildings.
Holmes gave a quiet snort.
“A shabby fellow. An exceptionally nasty piece of work. The last person whom I would put in charge of children. Fortunately for our client, as I think Patrick Riley must now be called, Winter has made a strategic error. He would dearly love to massage the tale of attempted suicide into a confession of guilt. That would end the matter. He is too stupid or perverse to see that it is his weakest spot. It is where I believe we shall find the loose thread that unravels this entire conspiracy.”
“Conspiracy?”
“What else? There is far more to this than Winter’s obvious defects of character.”
The so-called School Field, which was not strictly part of the grounds, was rough going, with chalk under a few inches of soil. It looked useless for crops or pasture, or indeed for anything else. The grass grew in brief, uneven tufts, and the broad path was something like a disused cart-track.
To judge from the present state of the earth, the rain that had spoilt so many cricket matches in the northern and eastern counties last week had probably cleared the Isle of Wight a day or two earlier. Patterns of footsteps left on the muddy surface the previous Sunday had accordingly been dried and hardened by a steady south-westerly breeze from the English Channel. Among these prints must surely be those of Patrick Riley and, indeed, whatever so-called witnesses there may have been. If Reginald Winter’s order putting the field out of bounds had been obeyed, as I felt sure it would have been, the latest prints must necessarily have been preserved for a few days.
We walked almost half-way across the field, following the track, before Holmes stopped and surveyed the path ahead. It is necessarily true that more people will cross the first half of a field than the whole of it. Where we were standing, there were three prominent sets of prints which were continuous and a number of others which appeared from time to time on the track, as though someone had been walking at first on the grass but occasionally on the path. My companion stood there for a moment, staring down at these foot patterns. He looked up.
“I believe, Watson, that we have found our man, if Patrick Riley is he. Boys, being boys, will amble about all over the place, mostly on the grass of the field. But imagine that you were running to reach a particular destination on the far side of the field as quickly as you could, and that the surface was still damp from rain. You would, I think, prefer to follow the firmer ground and straighter line of the path. Would you not?”
“As you say.”
“It is so obviously the best way that while you were running you would hardly think about it. It is what you would do by instinct. In any case, if you were in such a hurry that it was necessary to run, then wet grass on either side would slow you down. Now then, you will see there are footsteps here which I have been following from a little way back.”
He paused, turned round the way we had come and then swung round again.
“See here. The length of the stride suggests the height. The depth of the impression in damp earth indicates the weight or build. What I have found is evidence of a lightly-built boy, about five feet six inches in height. At first, just for a little, the soles and heels of his shoes were equally printed, therefore he was walking. I have noticed several similar tracks, but his is consistent and therefore presumably the one we want. You see it here?”
I looked at the print of a business-like sole and heel, the plain uniform shoe of so many schools and colleges. At this point, however, the print of the heel was hardly visible and all the weight seemed to be on the toes. To me the stride appeared longer than that of a boy who was five feet six inches in height. In company with Sherlock Holmes, the explanation was obvious.
“By the time he got here, he had started running!”
“Indeed he had. Of course, there is nothing remarkable in that. Boys of his age, when they have leisure, are normally lazy. But they will run a few steps or a few yards in a game. However, ask yourself how many would run alone the width of a large field, almost start to finish, in a Sunday suit for no good reason. Everything here invites a stroll, not a run. According to the evidence, only Patrick Riley was seen to run towards the railway embankment last Sunday afternoon. See for yourself. There are no continuous running prints but these.”
He stopped again and glanced up at the light cloud veiling the pale Solent sky. I took the chance to intervene.
“That hardly tells us more than we knew already.”
“You think not? I believe it tells us a good deal more. Let us enumerate the details. So far, we were merely informed that he ran across the field. The foolish and improbable suggestion was an intent to throw himself under a train. It was not suggested, for example, that he was running away from pursuers or that he wished to avoid surveillance. If that was the case, his fear would not be that he might be late for the train which was going to kill him but that he wanted to avoid being seen or captured.”
Having demolished the theory of suicide for Winter’s benefit, Holmes now sought to replace it.
“I don’t entirely follow you,” I said.
“Just here, old fellow, there are two prints made by the boy who was running—whom we shall assume was Riley. They are the only ones so far that do not point forwards. The right foot is at a right angle from the path. The left foot also points right at a lesser angle. Now see here. Stand with your feet exactly where the prints are. It will not matter if you disturb the earth. You see? As you stand now, the slightest movement of your head or torso gives you a full view of the field behind you on your right. And a few yards further on our fugitive does it again—this time to the left.”
