Replica - Lionel Saben

Alfred Eberhard is renowned in his field of chromosome research. He is obsessed with keeping his genius alive long after his death.

 In his private laboratory, he has brought his dream of immortality to life--by creating the perfect clone, his exact genetic replica down to the last, chilling detail. "Orin" is the dead ringer of his creator--a child prodigy born with the same brilliant capacity to continue in his father's fiendish research.

They are alike in every way. Except for one terrifying difference. Orin has a diabolical mind all his own. And soon, the doctor will come face to face with his own worst enemy.

A well read worn copy.
