Fred and Dr Gull:

The man who is Jack the Ripper is of the upper class, the ruling class; the class that believes itself to be above the law and all common decency.  He is commanded by the Queen herself and no one dares to stop him.  He believes himself immortal, godlike and ushering in the twentieth century.

Fred Abberline has risen from the streets to become what he is; a young, drug-addicted, visionary who clutches at his personal grief.  He uses his opium induced visions to guide him but he also has another weapon at his disposal: his intelligence.  Driven by his nightmare dreams and a sense of chivalry, he pursues Jack through the dark streets of late Victorian London.  Fred has seen enough cruelty and suffering in his work, but Jack's excesses revolt even his world weariness.

Jack has his cunning, his wall of silence, protected by the great in society and he becomes ever more violent and brazen.  He even advises Fred and allows him to handle the very blade that slaughters poor Annie's friends.  Perhaps he sees the young policeman as nothing more than an amusement, never believing that Fred will find him out.  In the end, Fred discovers the identity of Jack and manages to cheat him of his last unfortunate victim.  Only to fall victim himself.  Fred has chased Jack all the way into hell.

Fred first suspects that a physician could be involved because the murderer seems to have an intimate knowledge of disection and the nature of the cutting inficted on the victim's suggests a surgeon,s knife was used.  He visits Dr Gull at a soiree given to raise funds for the "Elephant Man".  There, he speaks to Dr Gull about the investigation.  The doctor is friendly and affable, giving Fred a prescription for something to help his opium addiction.  Fred then visits the doctor in his own home, having tea with him and discussing the case again.  Finally, Fred realises who Jack really is and confronts Dr Gull in his home again.  But the doctor is protected and Fred risks his own life in trying to end Jack's.
