In Now You See It, the prolific master of suspense and screenwriting (I Am Legend; The Incredible Shrinking Man) delivers a knock-out tale the likes of which have not been seen since Henry Clouzot's devlilish thriller Diabolique. Some years ago, the Great Delacorte, a famed stage magician, came down with a stroke that left him in a vegetative state, able to move only his eyes. The entire action of the novel is witnessed through these eyes as Delacorte sits in the Magic Room of his country estate, a room custom-tailored to display stage illusions. Delacorte's son, Max, has taken his name and place as an illusionist in every effort to replace his father. Max is supported by his wife Cassandra and her amazingly identical lookalike younger brother Brian. But for the past year, Cassandra has been poisoning Max's food with arsenic and a sleeping pill. She wants the act all for herself--but Max has his own ideas, and his revenge is the big dish that Matheson sets before us in this dazzler that offers top-flight fun!
