"Jeremy Wade is on the trail of a mysterious man-eater. New Zealand's fresh waters have been a safe place for swimmers, yet as Jeremy finds out, its remote rivers and deep lakes provide refuge for an ancient and slippery predator that can stay hidden for more than a century. To flush one out, he must put himself on the menu."
After reading reports of flesh-eating eels in New Zealand, Jeremy Wade journeys to a land which he always thought a safe place to swim. Captain James Cook's memoirs and Māori folklore's tell of man-eating snake-like creatures.
He treks into the Waitomo Caves and Lake Manapouri and discovers just how savage and dangerous these "devourers of men" can be. Armed with razor-sharp teeth which prevent escape, these eels spin and tear off bits of flesh like a crocodile.
Although he already knows they have the ability to cause serious harm, Wade still must determine if they have the attitude to attack a human in order to find out if they deserve their reputation. The only way to do this is to put himself on the menu.
