Five cream white parallelograms"" -- what are they? ""a water purification plant; the billing offices for Master Charge, an insane asylum?"" They're actually the headquarters of NESTER -- The New England Sensory Testing, Engineering & Research"" center which is a little of each of the above, a monitored mind control bureau where you come not to make friends but influence everybody through various kinds of manipulation and subterranean surveillance. Thus Paul Galambos, a psychologist, with a failed marriage and a faulty lack of self-esteem, applies to NESTER and is accepted even though before very long he is quickly disenchanted with a life lived ""from tick to rock"" in a climate of suffocating suspicion. Spencer handles all of this with a surprising degree of jauntiness under the sinister circumstances and it might remind you of the early David Ely -- it has just that quality of mechanized menace and unexpected danger rising up through your innersoles on the wall-to-wall carpeting in a world where we've sold our souls to nerve taps and transistors. Possible, isn't it?
