The Fellowship of the Frog by Edgar Wallace

Maitlands Consolidated had grown from one small office to its present palatial proportions in a comparatively short space of time. Maitland was a man advanced in years, patriarchal in appearance, sparing of speech. He had arrived in London unheralded, and had arrived, in the less accurate sense of the word, before London was aware of his existence.

Dick Gordon saw the speculator for the first time as he was waiting in the marble-walled vestibule. A man of middle height, bearded to his waist; his eyes almost hidden under heavy white brows; stout and laborious of gait, he came slowly through the outer office, where a score of clerks sat working under their green-shaded lamps, and, looking neither to the right nor left, walked into the elevator and was lost to view.
