I first read this book in third or fourth grade from my school
library. The stories were great -- the heroes were smart kids
who had adventures using science and technology. It was a kind
of adolescent fantasy for juvenile high achievers, and, as it
turns out, many future computer hackers (hackers in the original,
true sense of the word -- don't get me started...).
Decades later I had forgotten the title but remembered some of the
stories, and one day came across Mark Maxham's
where he had posted, for a time, scanned copies of three different
Mad Scientists' Club books. I spent the next hour reading all of
the stories while having flashbacks to grade school.
Alas, Mr. Brinley's children have renewed the copyrights to their
now-deceased father's works, and Mark took down the pages out of equal parts
fear of litigation and respect for the author.
Internet searches for copies of these books yield incredible asking
for a thirty-five year old Scholastic book (remember the color order
sheets from school that you'd fill out and return to your teacher?)
that most parents probably discarded.
I finally found a copy in a thrift shop. It's in pretty good shape,
with no missing pages and a good binding. The cover is slightly folded
here and there, and the name "Carol Myers" is neatly written in cursive
on the inside title page.
The stories are still entertaining and the illustrations by Charles
Geer are terrific.
Just a week later I found another copy, this time with no inside
illustrations and a cover by Leslie Morrill.
