“I am entirely at your service, Leroux,” he said. “I can quite understand how this ghastly affair has shaken you up.” “It was so sudden,” said the other, plaintively. “It is incredible that so much emotion can be crowded into so short a period of a man's life.”... Big Ben chimed the quarter after midnight. Leroux, eyes averted, walked to the writing-table, and took up the telephone. III INSPECTOR DUNBAR TAKES CHARGE Detective-Inspector Dunbar was admitted by Dr. Cumberly. He was a man of notable height, large-boned, and built gauntly and squarely. His clothes fitted him ill, and through them one seemed to perceive the massive scaffolding of his frame. He had gray hair retiring above a high brow, but worn long and untidily at the back; a wire-like straight-cut mustache, also streaked with gray, which served to accentuate the grimness of his mouth and slightly undershot jaw. A massive head, with tawny, leonine eyes; indeed, altogether a leonine face, and a frame indicative of tremendous nervous energy. In the entrance lobby he stood for a moment. “My name is Cumberly,” said the doctor, glancing at the card which the Scotland Yard man had proffered. “I occupy the flat above.” “Glad to know you, Dr. Cumberly,” replied the detective in a light and not unpleasant voice--and the fierce eyes momentarily grew kindly. “This--” continued Cumberly, drawing Dunbar forward into the study, “is my friend, Leroux--Henry Leroux, whose name you will know?” “I have not that pleasure,” replied Dunbar. “Well,” added Cumberly, “he is a famous novelist, and his flat, unfortunately, has been made the scene of a crime.
