Mark Baker at epinion has given MR. MONK IN TROUBLE a thumbs-up. He says, in part:
I often found myself laughing out loud or at least chuckling and smiling as I went through the book. But it isn't all laughs. Mr. Goldberg always does a great job with these characters, and he allows us several moments that are very touching and even enlightening about them. They continue to be real people very recognizable to fans of the TV show.
[…]I have enjoyed these books so much, I don't completely feel like I've lost Monk yet.
