The magic garden of George B

the long version

"The author presents a bombshell puzzle so startling that it seems inscredible that there could be any solution at all! But there is indeed a solution - moreover, one that requires a chain of lesser puzzles to be solved first. The reader is thus taken on a journey through a maze of subsidiary problems that has all the earmarks of an entertaining detective story. This book leads the unwary reader into deep logical waters through seductively entertaining logic puzzles"--Publisher's description.
