It might be because this book was hyped up to me so much, but I hated this in the end. The writing throughout was overwrought, using a lot of words to say very little, and being extremely long-winded in reaching the point of a sentence or argument.
Then there's the ending deductions, which I have trouble buying. The conductor is the person who everyone's eyes are on during the boarding of a bus (to give him money), so I find it hard to believe someone does not see the guy slip something into someone else's pocket (it's mentioned in the scene that people are waving their fares in his face and that he's shouting orders, so we know many eyes are on him). Then the glove is logical, but I still think an alternative like in a medicine bottle is possible too. Lane says a handkerchief is clumsy, but that doesn't mean it's not possible (and you can wipe any spare poison on some random seat or so). Not to mention, if you're willing to include other passengers, someone else could just use a long sleeve or something and wipe it. So I don't honestly like the deductive process that lead to identifying Woods on the bus.
I appreciate more the clue of the inconsistency of appendicitis scar from two years ago despite working straight for five years, as well as the clue of the ticket book being moved and the clue of Stopes' handwriting and Woods' handwriting being similar, but I still really dislike woods as the culprit.
I find the maintaining of three different identities while working non stop for five years very hard to swallow, especially with hours extending into each other and the legal papers needed to maintain such a thing. It seems like a very long and cumbersome way to commit the murders, waiting out 5y instead of doing it much faster and getting revenge sooner. He also targets Harley first instead of the man who murdered his wife, and he allows them to continue living for five years longer. If he has an alternate identity, he could just do the murder and stop living as that identity, using the one of the other two immediately.
Then there's minor things that I don't think lead anywhere. Some plots like Mrs. DeWitt's adultery or her superstitious nature don't ever get brought up again, and it's completely pointless. She doesn't even work as a red herring because Lane says himself "X" is a man and is the same as Martin Stopes.
Overall, honestly not a fan of the piece because of the ending deductions but also because of the unbelievability of the end and the poor writing. I find it very chunky and roundabout, using a lot of words to say very little. (I know it's common in other Queen's from what I've tried, but it just makes reading Queen extremely unfun.) I also don't like some assumptions the writers take in this, much like in Greek/Siamese as well, where I found some assumptions for the deductions to be questionable.
Anyway, it was extremely disappointing, and I'm surprised this was top voted in one of the Japanese polls I saw. It makes me want to try other Queens less. I'm not sure, but I'll think it over. I may not bother reading any more Queen - we'll see. (Side-note but about 1 month to read all of this, which is about average for me, so at least, it reads a smidge better than Greek, but it's still pretty bad IMHO.)
EDIT: also, the way the police question people is so dumb. I thought this in Greek Coffin, but the inspector uses zero subterfuge. He keeps people in same spot, so there's no chance of catching out contradictions, then applies no tricky pressure. Ex when cornering Collins, he outright tells him Dewitt's murdered, instead of waiting for collins to reveal more (and collins WAS IN THE MIDDLE OF TALKING of what he did wrong, essentially). I think it's more because the writers are garbage at actually writing these kinds of scenes. They always write scenes very literally and directly, but they don't actually know how to be clever with dialogue. They're only good at hiding details/inconsistencies in the army of bloat they have in their piece.
Side note, but the dying message was supremely mediocre and not good with some wild leaps to construe. I also checked this in a word count doc, and it was about 97k words, which really is too much. This truly is just too wordy.
EDIT again: Also, why the eff did Woods send threatening notes in his own handwriting? If he wanted to scare DeWitt, he could use a typewriter, and then he risks no chance of being traced via handwriting. and DeWitt not going to police is dumb in the first place. From his point of view, he could just say it's a murderer who DeWitt helped capture and put into prison, then the murderer escaped and he, DeWitt, seeks protection. It's also strange that he caved to Longstreet's blackmailing from this. Longstreet is in the same boat, so it's not like Longstreet can start talking about the crime the three committed. The more I scrutinized this, the more holes and issues I find. It REALLY makes me want to not bother with more Queen.
Oh, everyone was searched right? So then the wig would be detected the moment police run their hands through the guy's head. Once it's noted down (and I assume they noted down what was searched), they'd realize an inconsistency with the body pulled from the river having actual red hair.
