He is an extraordinary little man! Height, five feet four inches, egg-shaped head carried a little to one side, eyes that show green when he is excited, stiff military moustache, air of dignity immense! He is neat and dandified in appearance. For neatness of any kind he has an absolute passion. To see an ornament set crookedly, or a speck of dust, or a slight disarray in one's attire, is torture to the little man until he can ease his feelings by remedying the matter. "Order" and "Method" are his gods. He has a certain disdain for tangible evidence, such as footprints and cigarette ash, and will maintain that, taken by themselves, they will never enable a detective to solve a problem. Then he will tap his egg-shaped head with absurd complacency, and remark with great satisfaction: "The true work, it is done from within. The little grey cells - remember always the grey cells, mon ami."
