And thus it came about that on that October morning I found myself in the deep level tube with the Professor speeding to the North of London in what proved to be one of the most singular experiences of my remarkable life.

I had, before leaving Enmore Gardens, ascertained by the much-abused telephone that our man was at home, and had warned him of our coming. He lived in a comfortable flat in Hampstead, and he kept us waiting for quite half an hour in his ante-room whilst he carried on an animated conversation with a group of visitors, whose voices, as they finally bade farewell in the hall, showed that they were Russians. I caught a glimpse of them through the half-opened door, and had a passing impression of prosperous and intelligent men, with astrakhan collars to their coats, glistening top-hats, and every appearance of that bourgeois well-being which the successful Communist so readily assumes. The hall door closed behind them, and the next instant Theodore Nemor entered our apartment. I can see him now as he stood with the sunlight full upon him, rubbing his long, thin hands together and surveying us with his broad smile and his cunning yellow eyes.

He was a short, thick man, with some suggestion of deformity in his body, though it was difficult to say where that suggestion lay. One might say that he was a hunchback without the hump. His large, soft face was like an underdone dumpling, of the same colour and moist consistency, while the pimples and blotches which adorned it stood out the more aggressively against the pallid background. His eyes were those of a cat, and catlike was the thin, long, bristling moustache above his loose, wet, slobbering mouth. It was all low and repulsive until one came to the sandy eyebrows. From these upwards there was a splendid cranial arch such as I have seldom seen. Even Challenger's hat might have fitted that magnificent head. One might read Theodore Nemor as a vile, crawling conspirator below, but above he might take rank with the great thinkers and philosophers of the world.
