Assassination is the murder of an individual; usually a political or famous figure. An added distinction between assassination and other forms of killing is that an assassin usually has an ideological or political motivation, though many assassins (especially those who are not part of an organised movement) also show elements of insanity. Other motivations may be money (as in the case of a contract killing), revenge, or as a military operation.

Way of the Tiger is the name of a series of adventure gamebooks by Mark Smith & Jamie Thomson set on the world of Orb. The reader takes the part of a young ninja, Avenger on his quest to avenge his foster father and recover the Scrolls of Kettsuin. Later books present fresh challenges for Avenger to overcome. Compared to other gamebooks such as those in the Fighting Fantasy series, Way of the Tiger provided a more developed storyline and atmosphere, as well as three-dimensional characters.
