Search - The Great Brain (Great Brain)

This is one of my favorite series and I've read it over and over again as a kid and now as an adult! You'll recognize the "rascalness" of a Tom Sawyer character. John, JD, tells of growing up in the late 1800's with his very clever, conniving brother, Tom, TD. You'll be impressed that this kid is able to figure out logical solutions to his and the adults' problems all while lining his pockets. In this book, TD rescues two boys, gets rid of a teacher and helps an immigrant and a injured boy better themselves. This book is the first in the series (the series is chronological) and all are worth the read! Unfortunately, starting with "Academy", the books are somewhat hard to find. The series is listed below:
The Great Brain
More Adventures of the Great Brain
Me and My Little Brain
The Great Brain at the Academy - My favorite, if I had to pick - GB vs. Catholic school!
The Great Brain Reforms
The Return of the Great Brain
The Great Brain Does It Again
The Great Brain is Back
