The monkey had a busy morning, but it was finally time to go home.
He was a small creature, about the size of a rabbit, with a long prehensile tail and dusky red fur. Earlier that day, scientists had scooped him up from his cage and taken him away to get a shot. But now that was done, and just like for many of us, heading home meant that he'd finally get to rest and hang out with his mate.
This time, though, his scientist colleagues weren’t done with him. In fact, our monkey was being set up for an incredible betrayal.
