Trying to find childrens books featuring three brothers named (I think) Alexander, Benjamin and Christopher?
Believe the three brothers solved mysteries, a triple threat Hardy Boys, they may even have been triplets. Trying to find author and titles. Looking to get my nephews reading books I enjoyed as a child.
I think it could be the books by Robert Arthur. He wrote the Three Investigators Classics–three boys who establish a detective firm with the motto "We Investigate Anything!"
