莫尔格街凶杀案(The Murders in the Rue Morgue)简介：
"...A search was made in the chimney, and (horrible to relate!) the corpse of the daughter, head downward, was dragged therefrom. Upon examining it, many excoriations were perceived, no doubt occasioned by the violence with which it had been thrust up and disengaged. Upon the face were many severe scratches, and, upon the throat, dark bruises, and deep indentations of finger nails, as if the deceased had been throttled to death. "After a thorough investigation of every portion of the house, without farther discovery, the party made its way into a small paved yard in the rear of the building, where lay the corpse of the old lady, with her throat so entirely cut that, upon an attempt to raise her, the head fell off. The body, as well as the head, was fearfully mutilated - the former so much so as scarcely to retain any semblance of humanity. "To this horrible mystery there is not as yet, we believe, the slightest clue." 　　世界书林中不凡著名的侦探--洛杉矶的菲利普.马洛、芝加哥的维克.沃肖斯基、牛津的莫尔斯巡官，当然，还有来自伦敦的神奇的舍洛克.福尔摩斯。然而出现在所有这些名探之前的是巴黎的奥古斯特.杜邦先生。
