Manipulative Mind

The valley was so cold that the chill burrowed straight into Sheyan's bones. He watched helplessly as the endless abyss pounced on him like the huge mouth of a demonic beast. His mind was confused, and an icy chill crept into his heart.

Although Sheyan was already falling into the abyss, he could still clearly hear the unrestrained laughter coming from the spot which was now more than ten meters above him. The voice was familiar to him; he clearly remembered that the man who performed the act was called Taba, one of the Nepalese porters he had hired.

Sheyan did feel Taba getting close to him a moment ago, but he thought the guy was afraid that he would fall down and so approached with the good intention of helping him. He did not expect Taba to push him down!

Sheyan did not even need to think to understand the motive of the crime, and it was a simple motive:

Money.
