chunk: Nineteen years later, the son of the murdered man, also Allan Armadale, rescues a man of his own age—Ozias Midwinter. The stranger reveals himself to Reverend Decimus Brock, a friend of Allan through his late mother, as another Allan Armadale (the son of the man who committed the murder). Ozias tells Brock of his desperate upbringing, having run away from his mother and stepfather (Mr. Neal). The Reverend promises not to disclose their relation to one another, and the young men become close companions. Ozias remains haunted by a fear that he will harm Allan as a result of their proximity, a fate warned of in his father's letter; this feeling intensifies when the pair spend a night on a shipwreck off the Isle of Man—as it turns out, the very ship on which the murder was committed. Also on the vessel, Allan has a mysterious dream involving three characters; Ozias believes that the events are prophesy of the future.
