The Story of the Kevin Case, by Andrea Slatt

Viner agreed to make a note of anything his sons might mention that could be of any interest to poli. He didn't think his sons had been playing down by the lake on the night kevan was killed, but robin insisted he was telling the truth. The boys were taken into separate rooms to tell police what they knew. Robin said there were two boys, one wore all black, while the other wore gray pants and a black jumper. Given that kevan had died by strangulation, this was obviously incorrect,. But police weren't prepared to rule robin's account out.
