As I mention in the “About Mostly Mysteries” section up top on the home page, Encyclopedia Brown was one of the first mystery series I remember reading, getting the books (if I remember correctly so many decades later) from Scholastic, ordered through the elementary school I went to. Clearly the series helped start something !!!
And right now the first book in the series, Encyclopedia Brown, Boy Detective, by Donald J Sobol, is on sale in the US for $1.99.
