As a female, what struck me most about this book was 'the lads'. I've been heterosexually married several decades but I still find 'the lads' as foreign as I would find walking about under a blue burqa in Afghanistan. So, this book ended up being kind of a National Geographic article for me on a certain level.
I tried to 'connect' with 'the lads' that the author created as the characters we were to be interested in, since they were the victims of prejudice and nefarious plots, but I found myself thinking a lot 'see what a mess you got yourself into?' In the end, I gave up trying for sympathy and read the story as about an exotic culture I cannot understand. I realize many 'lads' do very well later in life and that is when they make sense to me. However, because I kept expecting the four protagonists to die tarnished by their own blaring misdeeds, even if blameless of murder, I couldn't really connect at all. Most of my friends generally have been nerds and geeks, or activists or religious people, not that I haven't been friends with a variety of folks. 'The lads' types in my life did not seem as if they would survive their 20's, and to be their friend was expensive since they seem to destroy every room, every stick of furniture and other belongings or goods, cars, and gambled or drank up or smoked or snorted up their paycheck in a few hours. They invented the modern concept of meaningless sex before girls had a clue. They scared the crap out of me. McDermid obviously has an intimate insiders grasp of what 'lads' are, and kindly allows her lads to be seen as decent young men (deep down) for the first half, and as normal middle-class men later.
Anyway.
The lads are being lads, meaning getting as drunk as they can possibly get between vomiting fits (always makes it a challenge) at a party. They stole (borrowed) a classmate's car to get there, and then they tried very hard to talk the women at the party into a one-night acquaintance in a bed. Having enjoyed reaching a state of mental derangement where walking is peculiar, they stumble through a park after leaving the party and trip over a woman's body. The friends, Alex (Gilly), Tom (Weird), Davey (Mondo) and Sigmund (Ziggy) get her blood all over themselves since being drunk has made the processing of coordination a bit difficult. Being basically wonderful lads, they decide to get a policeman (at least three of them decide - Weird is giggling at how funny the woman looks because he got high on hallucination-causing drugs on top of the alcohol). The policeman takes a look and soon the 19-year-old men are under suspicion of murdering the barmaid. It seems two of them have been trying to get laid by her for some time. It doesn't help their offended and frightened protestations of innocence when the cops find juvenile records of laddy hi jinks and mayhem. The brothers of the murdered girl are not university lads like our heroes, but are pure small-time thugs who decide beating up and dumping our lads individually down into wells where they won't be found for three days will get them to confess when the police are unable to make them talk. However, the police clear up the brothers' muddy sense of injustice with threats of long terms in prison if they try anything like that again, so they slander the lads as much as possible. Three of the lads end up leaving the country when they graduate from college, profoundly affected by the suspicion heaped upon them as well as the vision of the bloody body, which haunts them when they sober up.
The second half of the book finds our lads no longer lads, but respectable family men earning incomes in respectable middle-class work. Then they begin dying one by one in 'accidents'. Oh oh.
A very well-written book which explores the psychological impact of a murder on four friends who never could resolve what happened that night to themselves or others. The quartet breaks up and only two maintain contact as the years pass; but when the quartet starts dying in accidents, the surviving lads know they need to find out who the real killer is. The question for us readers is, who will still be breathing by the last page? Hopefully it will be the one you liked best.
