The Mystery of the Stuttering Parrot by Robert Arthur, 182 pages

The 2nd book in the Alfred Hitchcock and the Three Investigators series. You can tell this book hasn't been re-published because of the stereotypes in the book featuring Mexicans and others. While not overtly racist, you can see how outlooks have changed significantly. Still, it's a fun read.

The Secret of Terror Castle by Robert Arthur, 179 pages

I remember reading the Alfred Hitchcock and the Three Investigators books as a child. So I was excited to read them again as an adult. They're campy and fun, and I enjoy them more now than I do the Hardy Boys books. I think I'll have to make my way through more of the series.
