The Thirst (novel)

The Thirst (, 2017) is a crime novel by Norwegian novelist Jo Nesbø, the eleventh in the Harry Hole series.
Plot.
The novel features a killer who returns from Harry Hole's past and whom he failed to apprehend previously, but with a frightening new method of killing his victims by biting the victim's body with manufactured iron teeth and, apparently, drinking their blood, similar to the classic idea of a vampire.
