figures and dots, devised from what is known in code-writing
world as a Pigpen Cipher. In fact, this type of cipher is the cen-
terpiece of a Masonic degree ritual called the Royal Arch Degree.
This kind of thing would have remained in the realm of a small
corner of the population if it hadn’t been for Dan Brown and
his novels. His fictional “symbologist” Robert Langdon took
the subject out of the realm of tweedy MENSA meetings and
made it both entertaining and exciting. From his “ambigrams”
in Angels & Demons and the “cryptex” of The Da Vinci Code to
the lost symbols of, well, The Lost Symbol, it’s not often that
arcane, dusty, and obscure knowledge gets to collide head-first
with mind-exercising fun in one package. It’s like two mutually
exclusive brains shot out of opposite sides of a particle accel-
erator and squashed into one terrific pile of pages, if your
stomach can pardon the potentially icky metaphor.
Out of two such colliding brains comes the book you now hold.
My friend Mark Koltko-Rivera is well-versed in the history, phi-
losophy, symbolism, and methods of secret (and secretive)
societies. He was hot on the trail of Dan Brown’s clues from
The Lost Symbol since the day they first appeared on the
Internet in the summer of 2009, and his online blog entries
about them were endlessly fascinating, exploring subjects far
deeper than just the surface answers to the puzzles. Mark has
a PhD in psychology and has specialized over the years in
“worldviews,” which are ways in which people make assump-
tions about reality and the effects of those assumptions. That
makes him uniquely qualified to look at a code or cipher and
see it differently than others do.
Denise Sutherland is a puzzle designer extraordinaire. Her puz-
zles, word searches, and designs have literally appeared all over
the world, and she has an endless fascination with words. She is
able to think differently about the way words can be jumbled
together. Of course, she lives upside down in Australia and is
married to an astrophysicist, which can only help when it
comes to standing complex word combinations on their heads.
The result is a book with which I think you’ll spend many happy
hours engaged in frustration and surprise. As for me, I have
every intention of taking this one to the beach. I’ll be easy to
spot. I’ll be the one in a Batman suit, staring into the book with
beads of blood forming on my cowl.
