Query: ECHOES OF FRANKENSTEIN

MUTATION is what Cook does best----horror in the medical world, perpetrated by a doctor who "was only looking to advance mankind". Dr. Victor Frank (cute reference to Shelley's doc) has developed a process in which he can enhance the genius of embryos, and even does this with a surrogate mother in coming up with his own son, VJ (Victor Jr.). However, within five years, Frank's other son, David, dies mysteriously from a rare form of cancer, as does Janice Fay, David's governess. In the present day, VJ acts like a little Hitler and it's not long before his Mom suspects something pretty evil going on. The plot moves along at a steady if not frenetic pace and by the climax, the ending is obvious. Is there a sequel? I have to check.Better than many of Cook's other novels of this time, including the abominable CHROMOSOME 6.
