Silver in the Blood (слэш)

Victorian London, 1888. Harry had just started studying medicine under Professor Snape on a full-year scholarship. Plucked out of his small Yorkshire childhood town, Harry travels to London to secure a better future for himself and the rest of his family.
During the witching hour, there are some extra lectures to sign up for; lectures on supernatural biology and medicine. It seemed far-fetched at first and Harry is sure the only reason he even attends is because he paid the tuition through till the New Year. However, with the constant lack of sleep, and a newfound friendship with young aristocrat, Draco Malfoy, Harry starts taking an interest in the strange events occurring throughout Whitechapel. Why is the Ripper murdering so many people? Why can the police not catch him? And why is Harry helping Snape dissect the mutilated victims in the dead of night for his supernatural biology class?
It isn't long before Harry starts to see things that aren't really there. Yet, for some reason, he finds himself drawn to Draco; the young man seemed to thrive when the sky was dark and the moon grew fat. There was no way that his new found friend was something akin to the horrors Snape was teaching him about -was he?
