The last one is based onInfiltration By Colin McLaren. Good read and details how he brought down Tony Romeo (who was later murdered) and Trimbole's son, amongst others. Another good read is Wired by Damien Marriott. Marriott was a younger officer who spent time undercover with McLaren. The thing is,it affected Marriott a lot differently. He talks about it in his book, and while I have the utmost admiration for him, people talk about him becoming a little unhinged during the sting.
