There was a knee-hole desk in the middle, and seated at it, with some papers and open volumes before him, was the benevolent old gentleman. His face was round and shiny, like Mr Pickwick’s, big glasses were stuck on the end of his nose, and the top of his head was as bright and bare as a glass bottle. He never moved when I entered, but raised his placid eyebrows and waited on me to speak.

It was not an easy job, with about five minutes to spare, to tell a stranger who I was and what I wanted, and to win his aid. I did not attempt it. There was something about the eye of the man before me, something so keen and knowledgeable, that I could not find a word. I simply stared at him and stuttered.

“You seem in a hurry, my friend,” he said slowly.

I nodded towards the window. It gave a prospect across the moor through a gap in the plantation, and revealed certain figures half a mile off straggling through the heather.

“Ah, I see,” he said, and took up a pair of field-glasses through which he patiently scrutinized the figures.

“A fugitive from justice, eh? Well, we’ll go into the matter at our leisure. Meantime I object to my privacy being broken in upon by the clumsy rural policeman. Go into my study, and you will see two doors facing you. Take the one on the left and close it behind you. You will be perfectly safe.”

And this extraordinary man took up his pen again.

I did as I was bid, and found myself in a little dark chamber which smelt of chemicals, and was lit only by a tiny window high up in the wall. The door had swung behind me with a click like the door of a safe. Once again I had found an unexpected sanctuary.

All the same I was not comfortable. There was something about the old gentleman which puzzled and rather terrified me. He had been too easy and ready, almost as if he had expected me. And his eyes had been horribly intelligent.

No sound came to me in that dark place. For all I knew the police might be searching the house, and if they did they would want to know what was behind this door. I tried to possess my soul in patience, and to forget how hungry I was.
