Considering the author is themselves a former British soldier, this is a reasonably even handed narrative in regards East Tyrone throughout the Troubles. Rather than just a simple goodies vs baddies approach, Trigg takes the time and effort to summarise the contexts in which events unfolded and decisions taken. While the actual incidents are described in detail, the human tragedy is not forgotten, and Trigg seems to take the route of offering explanations rather than excuses.
The book is reasonably well researched with just a few errors- for example he refers to the event at the Glengannon Hotel where one of the doormen was murdered in revenge of the killing of Billy Wright as a "Catholic youth disco". As anyone who was part of the Exit 15 (later Area 51) massive (and that includes me!) will tell you, while the flyers may have stated "This is Not a Rave" it was well known as a cross-community techno/hardcore/house/trance venue, attracting young folk from all faiths and none, and all parts of the North.
I did approach this book with even more curiosity than normal. As intimated above, I grew up in that area during this time and recognised a lot of the events that went alongside my formative years. Some of the individuals named within were folk I knew, or at the very least had personal connections at some level. There are at least three incidents listed in great detail in the book that I observed first hand (a bomb attack on the local barracks, lying in bed and hearing the shooting of a soldier up a radio mast and watching the tracer bullets as the Clonoe chapel ambush happened, which we had driven past less than an hour before). Some victims and perpetrators I knew either the individuals themselves or at least other family members- for example I worked with the offspring of quite a high profile operative mentioned throughout the book. So it is fair to say I read the book with an even more acutely attuned radar for errors or sins of omission and to be fair there were very few. This was helped by the wide range of individuals from differing backgrounds and with competing agendas who formed the main source of information in the book-it would have been a Herculean task to combine so many competing and, in places directly opposing viewpoints to put events in context and it is generally well done.
The only slight issues I have are a few small factual errors that I really only spotted because I was born and brought up in the area. My biggest gripe is how one element is ignored and that is the role of the UDR. While collusion is touched on near the end in regards the Crown Security Forces overall, the fact so many UDR members were also loyalist paramilitaries and until South Africa provided UDA, UFF and Ulster Resistance with arms later in the 1980s, they were the main source of weapons used to kill Catholic civilians as well as Republican paramilitaries. This was all noted even in British MoD reports as covered in Micheál Smith's recent "UDR Declassified" book. While not excusing the killing of off-duty and retired UDR members, these facts would have been useful as providing extra information in relation to motivations.
Overall this is a well balanced retelling of some very controversial events, and it even helps explain why things turned out the way they did. Trigg could have taken the easy route, and basically provided a book written more like a thriller just going into detail about what happened, since going further and asking "why" made his job more difficult and of course a target for populist eejits looking to score easy points by claiming such an approach is condoning some pretty horrible acts. Hopefully though, anyone with a titter of wit will see this as an good start to understanding why people acted in the way that they did. After all it is easy to condemn- to try and understand takes intelligence and courage, but is the only way we can actually progress forward.
