They tirelessly search for clues but every lead seems to provide no answers. Finally, she confides in a close friend, Bob Davidson. He has a sixth sense which brings back terrible memories of that day in Twyford zoo. A series of strange deaths attributed to animals confirm his worst fears, and soon he is involved in the hunt for the Bengal Tiger. The situation is discussed at the very top level. The Home Secretary together with MI5, grant Bob a free rein in putting together a force of Police, Special forces and eventually US Marines. Together they follow the trail of death and destruction to a secret government installation. Held within that complex could be the means with which to extinguish human life.
