I first read Encyclopedia Brown in the 1970s, so I was interested in how they stood the test of time.
The opening of the book still explains why Encyclopedia Brown is called that and how his father is the chief of police of Idaville. The 10 cases Encyclopedia Brown solves are copy written 2010 and so are new. I was able to solve a few of the cases myself: having to do with military time, dates- B.C., and the differences between the seasons in the Northern and Southern Hemispheres. Both, he and I did this through the powers of observation alone. No computers or cell phones required (or even mentioned). And he still only charges a quarter! The solutions to the cases are in the back of the book.
The illustrations have been modernized several times over the years, much as Betty Crocker’s image has been over the years.
STILL TOTALLY ENJOYABLE!
