DR. VAN AARD - He had no family ties, no one to ask permission of. There's no point in asking the medical authorities, I knew what their answer would be. But I had to test it, sergeant I had to test it, I had to! I operated on Joe Corey, implanted the device within his skull. Only one thing remained, The activation of the artificial component in Corey's brain. It had to be energised by a special high-frequency, high-voltage machine.
The experiment was at once a success and a failure.Joe Corey was returned to a certain level of normalcy, but his psyche, his personality was destroyed, he was a different person. More importantly, his apparently rational behaviour would suddenly give way to bursts of maniacal and homicidal fury. In these periods he was capable of unspeakable and subhuman acts of violence.
Sergeant Ward, you don't know the torment I have suffered carrying this awful secret with me.I know it will ruin me. I just had to tell you, I had to, I...
SGT WARD - I hope you're not making a pitch for sympathy, doctor...Seems to me that you're the monster here, not Joe Corey. You created and turned loose a homicidal maniac with an artificial brain whose every action is completely unpredictable.
You're right about one thing, doctor, you're through. Fact is, I'd like to lock you up right now, except I'm not quite sure on exactly what grounds to arrest you. But when the district attorney gets my report I'm sure he'll think of something. Good night, doctor.
