I must summit Mount Kilimanjaro before my rival guide, to win the ultimate prize.

We call it the Great Escape. The annual trip where my boss asks us expert travel guides to escort a group of privileged, uber-wealthy clientele on some far-flung expedition, a cut-throat contest for riches and glory.

But this once-in-a-lifetime trip was never about winning to me. I'm here for answers, even if no one is ready to give them up. By the time we reach the top I will have the truth, if it kills me.

THE QUESTION IS, HOW FAR WILL THEY GO TO KEEP ME QUIET?
