Outsmarting the protagonists time and again, the Vulture eventually oversteps when he has the Blue Men kidnap Zarkon's associates Scorchy Muldoon and Joey Weston.

James B. Hemesath feels the book "enjoyable, lightweight reading, ideally suited for a dreary winter weekend," but "[n]evertheless, this is not a novel on which to spend your least $12.95."

He notes that "[n]ames of characters and bits of humor drawn from pulp-era writing abound for those readers interested in such things," observing that the book title itself "involves a rather clever joke."

Summing up, Hemesath thinks the novel "might be recommended for younger readers as a present-day introduction to the pulp-style storytelling that was so popular in the bygone days ... [b]ut for the rest of us, [it] is at best a passable diversion.

"[2] Robert M. Price characterizes the Zarkon series as "five delightful novels ... Lin Carter's loving homage to Doc Savage and his creator Lester Dent."
