The book in question is "Across Time" by Donald Wollheim (as David Grinnell)

Key Quotes;

'This is the Master Cruiser 12-12-12'


"When the form of control which I represent was first invented, the very name given it by its makers was that of the Ever-Perfect Lieutenant. After me, there can be no crews."

For the record, it was released as an 'Ace Double' with the classic Invaders from Earth

You can read reviews of the story here and here.

  • And David Grinnell was a pseudonym (one of many) for Donald A Wollheim.
