The chance came just after dawn, when we halted at a little junction. I got up yawning and tried to open the door, till I remembered it was locked. Thereupon I stuck my legs out of the window on the side away from the platform, and was immediately seized upon by a sleepy Seaforth who thought I contemplated suicide.

“Let me go,” I said. “I’ll be back in a jiffy.”

“Let him gang, jock,” said another voice. “Ye ken what a man’s like when he’s been on the bash. The cauld air’ll sober him.”

I was released, and after some gymnastics dropped on the metals and made my way round the rear of the train. As I clambered on the platform it began to move, and a face looked out of one of the back carriages. It was Linklater and he recognised me. He tried to get out, but the door was promptly slammed by an indignant porter. I heard him protest, and he kept his head out till the train went round the curve. That cooked my goose all right. He would wire to the police from the next station.

Meantime in that clean, bare, chilly place there was only one traveller. He was a slim young man, with a kit-bag and a gun-case. His clothes were beautiful, a green Homburg hat, a smart green tweed overcoat, and boots as brightly polished as a horse chestnut. I caught his profile as he gave up his ticket and to my amazement I recognised it.

The station-master looked askance at me as I presented myself, dilapidated and dishevelled, to the official gaze. I tried to speak in a tone of authority.

“Who is the man who has just gone out?”

“Whaur’s your ticket?”

“I had no time to get one at Muirtown, and as you see I have left my luggage behind me. Take it out of that pound and I’ll come back for the change. I want to know if that was Sir Archibald Roylance.”

He looked suspiciously at the note. “I think that’s the name. He’s a captain up at the Fleein’ School. What was ye wantin’ with him?”
