spoken to a female of whatever age or station during these strolls is a grievous offence. So is breaking bounds beyond the limits set for a walk. I imagine it gladdens Winterâs heart to catch a handful of culprits for his delectation.â
Having met the man, I had no difficulty in accepting this analysis of his character.
âYet if he was here when Riley made his famous run,â I said, âwhy has he never mentioned it?â
âPrecisely. Unless my instincts deceive me, he was not spying on his boysâjust one boy. It was Patrick Riley, who had ventured out of the sanatorium for some reason of his own. I am entirely satisfied that the lad was not contemplating suicide. Far more likely he was attempting to meet someone. Winter would give a good deal to know whoâand for what purpose. And so would I.â
I thought about this for scarcely a moment before saying,
âIt canât see it, Holmes. Whether Riley was hoping to meet someoneâor even commit suicideâhow could Reginald Winter know in advance? As I understand it, the boy was incommunicado and he would hardly tell Winter himself. Unless he was there by pure fluke, Winter would not know what time to take up watch or even where.â
âWinter does not strike me as a man who does anything by a fluke.â
âWell, there you are. Even if he knew Riley had slipped away from the sanatorium and was running across the field, it would be far too late and much too obvious to start running after him. Winter could only spy on him at the railway bank by being in place here before him. And he could not do that unless he knew which way he was going to run and when he was going to do it. There is a hopeless inconsistency.â
âNo, my dear fellow, what lies at the heart of this is a mystery. It is an article of faith in our detective agency that all mysteries have a solution.â
He was looking back towards the stretch of line running on its embankment. If anyone was going to spy, I thought, this was certainly the place from which to do it.
âWe had best be getting back,â I said.
But he was still looking about him in this little enclosure. I had no idea what else he expected to find, nor, I think, did he. Presently he chuckled, relaxed and took out his pocket-knife. He was staring at an elder branch, or rather what remained of it. Someone had cut through it at a point where it was the thickness of a large thumb. The cut was recent, to judge by the light colour of the exposed wood. It suggested to me that a walker had improvised a stick for himself, perhaps in the muddy weather. The absence of wood shavings indicated that the stick had been cut to size from the bush without any immediate need for trimming or shaping.
âGoodness knows how many boys cut sticks and whittle them,â I said sceptically.
He opened his pocket-knife and cut a further length of the sapling, no more than three inches, for what good that would do. He slipped the cutting into his pocket, closed his knife and we began to walk back. Perhaps evidence of a kind against Winter had begun to accumulate in that cold rational brain. But evidence of what?
I thought we were going to walk back the way we had come, but Holmes set off on a path behind the hedge. This was parallel to the School Field though concealed from it. At the far end, a small iron gate opened into a domestic âchicken fieldâ where St Vincentâs grew its vegetables. A further gate let us into an enclosed lawn whose door was evidently the headmasterâs direct entrance to his own quarters. A hand-bell had rung and it seemed that the âcadetsâ were now released from their classes. They were curiously dressed, like child sailors in their blue uniforms. A few wore a grey, braided edging to the lapels and the hems of their âEngineerâ jackets.
In the corridor on which Winterâs study was located Holmes stopped again, as if to check his
