Holmes's eyes fairly glittered as he spoke, and he put his hand over his heart and bowed as if to some applauding crowd conjured up by his imagination. "Criminal cases are continually hinging upon that one point. A man is suspected of a crime months perhaps after it has been committed. His linen or clothes are examined, and brownish stains discovered upon them. Are they blood stains, or mud stains, or rust stains, or fruit stains, or what are they? That is a question which has puzzled many an expert, and why? Because there was no reliable test. Now we have the Sherlock Holmes' test, and there will no longer be any difficulty."

Author Biography

Sir Arthur Ignatius Conan Doyle (1859 - 1930) was a British writer best known for his detective fiction featuring the character Sherlock Holmes. Originally a physician, in 1887 he published A Study in Scarlet, the first of four novels about Holmes and Dr. Watson. In addition, Doyle wrote over fifty short stories featuring the famous detective. The Sherlock Holmes stories are generally considered milestones in the field of crime fiction. Doyle was a prolific writer; his non-Sherlockian works include fantasy and science fiction stories about Professor Challenger and humorous stories about the Napoleonic soldier Brigadier Gerard, as well as plays, romances, poetry, non-fiction and historical novels. One of Doyle's early short stories, "J. Habakuk Jephson's Statement," helped to popularize the mystery of the Mary Celeste.
