The book is still in print, and I recently obtained a copy of the book through Amazon, from which I scanned the illustrations you see here.
Based on the CIA’s memo, my initial assumption was that the book (subtitled “Blackie, Brownie, and Whitey”) was intended as an indoctrination tool in an era when racial politics were coming into the mainstream. Please understand that by no means do I think the book had the power to turn children into little Manchurian Candidates. But it was one of many, many pieces of propaganda produced by the security apparatus of that time.
Here are selected lines of dialog from and description of each of the three horses. You tell me if you see a theme here:
Then Whitey, who was always the cleverest of the three, cried out excitedly: “I know what we should do!” (pages 8-9)
“Don’t be so scared,” cried Whitey. (page 9)
They trotted around the field, and then they took turns jumping over the chair. One …... Whitey sailed over the chair with ease. Two …… Blackie sailed over, but not so easily. Three …… What happened then? Brownie kicked over the chair and knocked it over! (page 12)
“Oh let’s go down there!” cried Whitey. Blackie looked a little doubtful. (pages 27-28)
Then Peter taught them to walk on their hind legs, for now that they were princesses they must walk on two legs instead of four. Whitey and Blackie learned quickly, but Brownie was more awkward. “Let’s not go into the town after all,” Brownie said in despair. (page 35)
These racial overtones aren’t the only evidence of dark arts in the book. There are some indications the Dutch author of the book, whose pseudonym is “Piet Worm,” collaborated with the Nazis in Amsterdam during the Second World War.
And amazingly enough, “Piet Worm” is a Dutch anagram for “Primo Wet”—“First Law” in the English. As any student of secret societies will tell you, “First Law” is a motto used by the Masons to indicate they considered themselves the Elite, beholden to no government or institution on Earth.
A couple of other quick notes from my initial reading of “Three Little Horses.” I’m not trying to paint a grand conspiracy theory here, only to note that the book is filled with the black humor and inside jokes so common among the puppet masters.
In one scene, Peter (who is a stand-in for the author) hides inside a fruit tree with a hidden door, and then surprises the three little horses by speaking to them from the tree. That’s a Garden of Eden reference—the Creator “hiding” in the Tree of Life—and another indication of the Elite’s conception of itself as godly, above the world.
There's also a masquerade straight out of "Eyes Wide Shut," a discussion of horse meat being sold at a butcher shop, and a prison scene that--I don't know--seems a little jarring for the target demographic (see the illustration at the top of this entry).
Opposite the dedication page is a simple, unexplained illustration of a honeybee, yet no honeybees appear in the story's text or illustrations. For what it's worth, the honeybee has been the calling card of the Cathars and Weavers for almost 1,000 years.
