Scissors

When he was a boy, Stuart Mullond's mother held him down while his urologist Dr. Ferguson performed a medical procedure on him that was so traumatizing and humiliating that its painful memory stayed with him for decades. For his entire life, his nightmares have been haunted by the snick-snick-snick of the doctor's scissors.
Now a divorced, unemployed adult with a troubled teenage son, Stuart is trying to hold his life together...when Dr. Ferguson suddenly shows up again. He's not confined to nightmares anymore. He's very real. And he is determined to perform that same horrible procedure on Stuart's son. But all these years later, Dr. Ferguson looks exactly as he did when Stuart was a boy. And he's kept his scissors nice and sharp ...
Snick-snick-snick!
