60s sci-fi android and crime

[Mike]

year read was 1969. the book was divided into 2 titles. One book was published upside down from the other book in paperback form. a part human/android has super strength when he activates plates under his arms and it gives him super strength and speed. aimed at young readers.

Sounds like an Ace Double - this is a list of all ACE doubles https://en.wikipedia.org/wiki/List_of... which narrows it down a bit. Do you remember the other story in the book?

Mike, that's a good start. Please add more plot details (from your comments) to the topic header (title), so someone can recognize your book from that description alone. Many members only read the headers.

We have thousands of book requests. We close threads with vague headers.
