The Dangerous Hour is a Sharon McCone novel. It's been a long time since I read one of these. Last time I read Muller, I seem to remember Sharon was a struggling investigator for All Souls. Now she owns a successful agency with offices and a staff. I lost touch. She's still not married to Hy though.
This book is about revenge. Someone Sharon brought down is out to return the favor and he's willing to kill to accomplish it. There's plenty of suspense and the usual cast of characters. I enjoy Muller but somehow I drifted away. Probably because so much time is spent in romantic and family angst. I like detective stories about detecting and not relationships. I still enjoyed the book. Recommended.
