This is an example of the current trend of heroism with extra grime and gloom, and there's a series by this author alone with the same spin on a slew of classics. I like the titles, I didn't finish this one, I won't read more.
The prose is full of jarring errors, suggesting that it wasn't sold by the word so much as by the stopwatch. For instance, a woman described as 'unbecoming' when Rosenberg clearly means 'uncomely'.
The descriptions of the not-three-musketeers' not-heroism lag, and I'm having a hard time deciding why, especially in comparison to pointless paragraphs in The Oakdale Affair. I think it's a failing of perspective; the characters are purportedly soliloquizing to themselves about behavior they unthinkingly accept... so really they're soliloquizing to us, but they aren't that sort of character. Dunno.
Now that I think of it, The Three Musketeers in the original are fairly horrible people, but it's easier for a modern reader not to notice because they really do unthinkingly accept their cruelties. Also, of course, keeps everyone busy, having seemingly been paid by the pound.
