this was surprisingly good! the main reason i bought this and picked it up to read it is because i thought it was going to be one of those shitty old mysteries. the ones that don't really stand to the standard set by the great mystery writers of the time, like sayers and christie.
however, this was nothing like that! it was actually quite good, even though i would say it's more of an anti-mystery, where you know who committed the crime, and it was quite thrilling. i really like armstrong's gripping beginning and the level of excitement and thrill throughout is pretty good; we're immediately thrown into the problem and, as we go along, we get to know these characters and their motivations for this investigation.
something i rather liked was the social commentary that i am not sure if it was intentional or not. the way that the murderer is a rich man, and people are choosing to believe him over the people bringing (slightly flimsy) proof against him, i found that very interesting. there was also a certain passage towards the end of the book, something that francis was thinking of, that i also really liked because it was a very interesting opinion and criticism.
another thing that i really liked was that we got a good amount of the story from matilda's perspective, and, i have to say, i think armstrong did a wonderful job at capturing the utter horror that tyl was going through in this book. her situation is understandably frightening and her feelings are captured and written in a great way; you, the reader, can really feel and see, you can visualise, why she's thinking this way.
i would say that the character writing isn't necessarily impressive, but it's decent enough for a mystery or for a thriller, where the characters are playing a role in a storyline than just- existing normally.
overall, this was quite nice! i can understand why this got a movie adaptation, i think it would translate really well into that medium because of its pacing and the thrilling events that take place. i think i'd recommend this to people who already like mysteries and thrillers; i don't think that this would make a good introduction to these genres per se.
