As the PI raised the camera and looked through the light-adjusted lens, though, he couldn't be more surprised by what he saw. Because, the two people in bed were Denise Brewster and ... a little boy! The PI watched as the middle-aged woman thrust and heaved with the young boy of ... what? Nine? Ten years old?
The PI had seen some sick things in his life, but the sexual abuse that Denise was doing to this boy ... it made him violently ill. But he pushed onward and took the pictures anyway.
He retreated back into the bushes, thinking about the ramifications of what he just saw and had evidence of. He supposed that Richard was off the hook for having an affair, but this was the sort of thing that could destroy Denise's career.
