Killer (1979) by Peter Tonkin - book

Peter Tonkin an author better known for his series of adventure and mystery books started off his career with this pulp horror story about a killer whale. When we first read about Killer it gave us strong Orca vibes, which is one of the weirder Jaws knockoffs. In any case, according to the folks on Goodreads it's a fun tale... no pun intended

Mass market paperback.
