The international relations depicted in the book have some basis in truth. In the real world, countries were jockeying for power and influence, and the book uses this as a backdrop. For example, the power struggles between different nations and the concerns about political stability are all things that were happening in real life at the time and are incorporated into the story. Also, the general idea of a hired assassin being used for political motives was not unheard of in that era, and the book takes this concept and builds a complex plot around it.

There was a jackal family in a thick jungle. The youngest jackal was always getting into trouble. One day, while the other jackals were out hunting, he wandered off. He came across a beehive. The sweet smell of honey attracted him. Without thinking, he tried to reach for the honey. But the bees got angry and started stinging him. The little jackal ran away as fast as he could, yelping in pain. When he finally found his family, they helped him soothe the stings. From that day on, he learned to be more careful.
Once upon a time, there was a jackal named Jax. He was very clever. One day, he saw a group of lions fighting over a large prey. Jax came up with an idea. He started howling in a strange way. The lions got distracted and thought there was a bigger threat nearby. They ran away, and Jax got the prey all to himself.
