This book reminds me of a really good Twilight Zone episode. A frazzled mathematician, who is working for the gov't on "the turbulence problem," comes home from work late one night to find someone else occupying his life, and groups unknown out to get him. What is going on? Is he losing his grip on his mind? Has his work involved him in a great spy conspiracy? Who can he trust and how can he escape when it seems the whole world isn't what he thought it was. It's a fast read, perfect for a plane ride, a day at the beach or a rainy Sunday.
Richard Matheson has written one of the most creative suspense novels I've ever read! He keeps you guessing in a game of plot twist and counter-twist that doesn't let up! Deceit, betrayal and romance. What every good thriller requires!
