This story begins in December 1997 in Primorye, a forested and mountainous region in South East Russia. It is an area where Siberian tigers reside and a group of armed men are driving in the snow, responding to an urgent message about a tiger attack.
The men were part of an Inspection tiger unit, established three years previously to investigate crimes involving tigers.
The Siberian or Amur tiger is the only one of six types of tiger that is suited to an arctic climate. It can swim for miles and kill animals many times its size.
