Another Ira Levin. This time he does science fiction. Is there any genre he hasn‘t done? Hats off it‘s a great story told in the sublime Levin way. And when you think it was first published in 1970, it‘s staggering. He creates a future world with frightening prescience. Points off for one violent and in my opinion unnecessary scene. And possibly The boys from Brazil has more science but I haven‘t read that yet. This is a pick for me.
