From the inside cover:

WHAT IS THIS "THING"...?

Q: IS HE GOOD OR EVIL?

A: He ravishes and kills. On the other hand, his love gives superlative bliss. And he speaks with the words of philosophers.

Q: DOES HE HAVE HUMAN SHAPE?

A: He is thought to be made of metal.

Q: WHERE DOES HE LIVE?

A: In an enormous junk yard occupying the marshes along Jamaica Bay.

Q: HAS HE ALWAYS MADE HIS HOME THERE?

A: He is known to have resided in Peru, where he performed evil rites with young Indian girls.

Q: IS HE REAL OR IMAGINARY?

A: One man, at least, claims to have seen him. Or a part of him.

Q: AND THE WOMEN?

A: Girls knew him, but never lived to tell about him.

Q: WHY HAVEN'T THE POLICE CAUGHT HIM?

A: They thought they did - in the form of a human fiend.

Q: THEN HE IS STILL ALIVE?

A: Could be. Watch out there - BEHIND YOU!

Yes, this reprint of Reed's book The Metal Monster Murders, retitled, slapped with a salacious cover and "especially adapted for your reading pleasure" appeared as part of the Uni Book series. It's not as sexy as it tries to appear, but is pretty interesting.
