Two incredibly wealthy brothers, one insane and dangerous (because you know that's the function of mental illness in mysteries) and the other terrified of his brother. An amateur sleuth who interrogates suspects and is tolerated, even reluctantly encouraged by the police who are dimmer than the amateur sleuth. A basset hound who attends the interrogations and comments in a cute doggie way. Dialogue that is sometimes snappy and sometimes just makes the protagonist seem highly irritating.

Apparently this isn't my kind of book, given the praise other readers have for it. I had trouble getting into it and set it aside. Picked it up again and began to enjoy it mildly, thinking it would be a solid three-star book. Then the ending ... well, to me it was sloppy and cliched and dreadful. And a disappointment as I have previously enjoyed the author's work, though this is the first I've read in this series. Sorry for the grumpy review, but I really felt highly annoyed by the end.
