Having finished today The Moonstone, I must say it was a very enjoyable book. The characters are not as quirky or memorable as Dickens's but it doesn't matter because the plot holds together remarkably well. Explaining of a certain laudanum incident in the novel caused almost unbearable tension which was resolved satisfyingly. Odd how it worked even though I predicted it. The ending was maybe a bit rushed, odd considering how slowly the narratives moved along generally, causing this to be relatively long novel for a detective story.
I'm a bit undecided whether this work has some pretty racist elements mixed in or whether the entire point of novel is to be anti-racist. It seemed a bit ambiguous, kind of like The Searchers. And that's how I like it best.
Edit: My next Collins novel will most likely be "No Name", which I've heard is ranked among his top four novels, like "The Moonstone". It may take some time however, before I get to it, focusing currently on Mark Twain.
