In less than ten minutes after he had issued from that building, fierce and crackling flames were bursting forth from its doors and windows. The streets echoed with the cry of _Fire_--the deep-toned bell of the City Hall filled the air with its notes of solemn warning and the fire engines thundered over the pavement towards the scene of conflagration. But in vain were the efforts of the firemen to subdue the raging flames; higher and higher they rose, until the entire building was on fire, belching forth mingled flame, and smoke, and showers of sparks. At length the interior of the building was entirely consumed, and the tottering walls fell in with a tremendous crash. The extensive warehouse of Mr. Paul Hartless, with its valuable contents, no longer existed, but had given place to a heap of black and smoking ruins! The reader is now acquainted with the manner of the Dead Man's escape from Sing Sing State Prison, and the circumstances connected with that event. CHAPTER XIII _The African and his Mistress--the Haunted House--Night of Terror._ Nero, the African, still remained a prisoner in the vault beneath Sydney's house. He was regularly supplied with his food by Dennis, who performed the part of jailer, and was untiring in his vigilance to prevent the escape of the negro under his charge. One afternoon a boy of apparently fifteen or sixteen years of age called upon Dennis and desired to speak with him in private. He was a handsome lad, of easy, graceful manners, and long, curling hair; his dress was juvenile, and his whole appearance extremely prepossessing. The interview being granted, the boy made known the object of his call by earnestly desiring to be permitted to visit the imprisoned black. 'Is it the _nager_ ye want to see?' exclaimed Dennis--'and how the devil did ye know we had a nager shut up in the cellar, any how?' 'Oh,' replied the boy, 'a lady of my acquaintance is aware of the fact, and she sent me here to present you with this five dollar gold piece, and to ask your consent to my delivering a short message to the black man.' 'Och, be the powers, and is that it?' muttered Dennis, half aloud, as he surveyed the bright coin which the boy had placed in his hand--'I begin to smell a rat, faith; this gossoon was sent here by Mr. Sydney's blackguard wife, who has such a hankering after the black divil--not contented with her own lawful husband, and a decent man he is, but she must take up wid that dirty nager, bad luck to her and him! My master gave me no orders to prevint any person from seeing the black spalpeen; and as a goold yankee sovereign can't be picked up every day in the street, faith it's yerself Dennis Macarty, that will take the responsibility, and let this good-looking gossoon in to see black Nero, and bad luck to him!'
