This is the second story to feature Mort and Ramon, and I enjoyed seeing them again. Having Ken and Sandy interact with other recurring characters adds an extra dimension to the story.
I really enjoyed this one.
I like this passage from page 21.
"Let's give it up," Sandy suggested. "Neither of us has the slightest idea of what he was trying to do, or why. And we never will."There is no doubt about that.
"I guess not. We'll just have to file it away among 'Unusual Incidents,' " Ken said.
Sandy sighed. "Sometimes I think that practically everything that happens to us is unusual."
It's interesting how very little I remembered about some of these books upon this reading. I had no memory of the plot of this book during most of my reading of this book. In fact, at one point I questioned whether I had read the book before. I knew I must have, since I was certain that I had the complete set when I read the books before. It was not until I reached the scene where the boys were hiding in the house and Ken called the police quietly on the phone that I remembered that scene. It's like the last few chapters were the only part of the story that made an impression on me before.
This book flows quite well, and I greatly enjoyed it.
