This was supposed to be about four retired couples, cops and wives, living in Florida and solving crimes (not cases). But Spillane turned it into a study of memory. Imagine a blinded amnesiacal lover secreted away inside a community of retired cops in New Jersey, and rediscovered by her old boyfriend after 25 years? What remains when memory disappears?
How does one lover make himself remembered to another?
If the boyfriend has the grainy voice of Richard Ferrone, and the nouns of a Mickey Spillane novel: doll, honey, kitten, what remains is instinct. And the girlfriend responds to being called a specific name by a specific voice. Hey, doll. All right, kitten.
