The Strange Case of Dr. Jekyll & Mr. Hyde- Robert Louis Stevenson

As you stroll along the streets of London in the company of lawyer Utterson and his distant relative Enfield, the latter narrates a gruesome tale of assault he had witnessed some months ago. The tale describes a dreadful looking sinister man, Mr Hyde, who ruthlessly tramples a young girl and disappears behind a door. A moment later he reemerges to pay off her relatives with a cheque drawn from the account of a reputable gentleman, later identified to be Utterson's client and old friend, Dr Jekyll.
