Culverton Smith

“It may surprise you to know that the man upon earth who is best versed in this disease is not a medical man, but a planter. Mr. Culverton Smith is a well-known resident of Sumatra, now visiting London. An outbreak of the disease upon his plantation, which was distant from medical aid, caused him to study it himself, with some rather far-reaching consequences.” (Sherlock Holmes)
I saw a great yellow face, coarse-grained and greasy, with heavy, double-chin, and two sullen, menacing gray eyes which glared at me from under tufted and sandy brows. A high bald head had a small velvet smoking-cap poised coquettishly upon one side of its pink curve. The skull was of enormous capacity, and yet as I looked down I saw to my amazement that the figure of the man was small and frail, twisted in the shoulders and back like one who has suffered from rickets in his childhood.

The mention of my friend’s name had an extraordinary effect upon the little man. The look of anger passed in an instant from his face. His features became tense and alert.

The man motioned me to a chair, and turned to resume his own. As he did so I caught a glimpse of his face in the mirror over the mantelpiece. I could have sworn that it was set in a malicious and abominable smile. Yet I persuaded myself that it must have been some nervous contraction which I had surprised, for he turned to me an instant later with genuine concern upon his features.
