Firecracker Jones Is On The Case

I purchased Firecracker Jones is on the Case for my grandson who likes to read. He prefers books that don't look like children's books even if he is 9 years old and this book was one he couldn't put down after I gave it to him when his family came for a day visit. I thought he would put it in his backpack after saying thanks but he got lost in the book after the first word, Vanished! I heard of Christopher Klim from his connection with Hopewell Publications important Best New Writing series and his praised novels but didn't know he wrote for children also. My grandson's preoccupation with it made me read it after he was finished. Klim's a master writer as well as a talented illustrator.
