Killer Crabs: The Return is a novel written by Guy N. Smith. It was first published in 2012. It is the seventh "Crabs" novel.
In 1978 the Crabs attacked Australia's Great Barrier Reef with horrendous loss of human life. Amongst the fatalities was Harvey Logan, big-game hunter. The world believed that these terrible crustaceans had been annihilated but Harvey's son, Brock, was sure that one day they would emerge from the oceans once more on a rampage of bloody carnage. Brock was also a hunter and he waited patiently for three decades. He wanted revenge as well as a Crab trophy for his collection. Then the crabs returned, this time on the Solway Firth and Brock's hunt began.
