Larkwood Report, a study of unusual psychic and related phenomena, as described in The Grail Conspiracies

I left the university area and wandered back to the business district of
Oxford. I had plenty of time before the meeting, so stopped in a
bookshop and asked one of the clerks if they had anything on the
Larkwood Report.

Her look suggested I’d asked for something particularly kinky, then led
me to a section that seemed to be on the cusp between modern history
and the paranormal. A peculiar spot for it, but as I quickly found out, the
so-called Larkwood Report was a very peculiar subject.

The first mentions were in books by professional debunkers, and they
treated Larkwood as a joke on the True Believers and Conspiracy
Freaks who took it seriously, along with all the other myths and legends
the debunking establishment considered wacky, stuff like UFOs, aliens,
the mysterious doings at Area 51, conspiracies by the World War II era
OSS and the current CIA, and that whole bunch of supposed
conspiracies.

From those books and others, I pieced together that the Larkwood
Report was a legend, butonly a legend: there was no proof that there
ever had been such a report, no official confirmation, nor even official
denial.

Legendary or not, a cult following had sprung up around the Larkwood
Report, people convinced that the same forces within the U.S.
Government that refused to release the bodies of the aliens who
supposedly crashed in the desert at Roswell, New Mexico, in 1947 were
also covering up the truth of what Larkwood had found in the ruins of
Nazi Germany, when, by some accounts, he worked for the OSS, which
was later to evolve into the modern CIA

The Roswell incident in 1947, the Larkwood Report of 1946, and the
disappearance of Paul Tapscott and whatever he found around 1944.
All three in roughly the same mid-1940's time-frame. Coincidence or
conspiracy?

The Report that supposedly didn’t exist got its unofficial name from Dr.
Horace Larkwood, a psychology professor who had served as a civilian
employee of the U.S. Government during World War II, doing unknown
research.

From later in The Grail Conspiracies:

Larkwood began by putting his report in context. It was 1945. The war
with Germany was drawing to a close, but the threat loomed of a new
conflict with Stalin. The Americans, the British, and the French all set up
teams to sweep through Germany to grab the Nazi technology before
the Russians could cart it away. As much as the Nazis were hated, the
German technological advances were respected, even to the point of
awe.

Most of the interest centered on weaponry: rocketry, aircraft design, the
German atomic program.

But there were indications that the Germans had been doing some work
on another kind of science. “For want of a better term, we referred to
that as ‘intangible science.’ That intangible science was the focus of
what’s come to be known as the Larkwood Report.”

“Intangible science? I haven’t heard that term.”

“Ever hear of the Foo Fighters?”

“Foo Fighters? The rock group?” The Foo Fighters came along in the
mid-1990's, definitely not the World War II era, and I wondered if this trip
was a waste of time. Maybe Larkwood was terminally confused.

“No, no, I’m referring to the real Foo Fighters. Around the end of ‘44,
American bomber pilots flying over Germany began coming back with
stories of little balls of light that suddenly began appearing around their
planes. Some described them as energy balls, others as flying crystal
balls. Somebody dubbed them Foo Fighters, and the name stuck.”

“They sound like UFO’s, like flying saucers.”

“Those terms came along only years later. Officially, the powers-that-be
within the military pooh-poohed the idea of Foo Fighters. But that was
just for public consumption, the usual show of bravado to calm the
troops. In private, the brass definitely wanted to know what the hell was
going on. Were these balls of energy bouncing around in the skies
some kind of Nazi secret weapon? Maybe some sort of a death ray that
hadn’t quite been perfected? In short, what in blazes had the Krauts
come up with?”

Larkwood shook his head, took a breath, and continued. “But there
were other crazy things the Nazis had been exploring. ‘Crazy,’ that is, if
you operate only from a conventional world view. But were they really so
crazy, after all? That’s what some folks in the government sent me to
find out.”

Incidentally, if you're intrigued by the OSS and its operations, I
highly recommend the following. While they are works of fiction,
they were written by people who not only tell good stories, but,
more importantly, have obviously done their homework.

By W.E.B. Griffin, the "Men at War" series, following OSS agents
in Europe and Asia during World War II. Titles include The Last
Heroes, The Secret Warriors, The Soldier Spies, and The
Fighting Agents.

Also by W.E.B. Griffin, another series, "Honor Bound," this set
mostly in South America, during World War II: Honor Bound,
Blood and Honor, Secret Honor.

By Charles McCarry, said to be "America's best spy novelist"
these which I have recently re-read include, The Tears of
Autumn, The Last Supper, and The Secret Lovers. While the
time-frame is later than the OSS, which morphed into the CIA
after World War II, most of the key characters had begun during
OSS times. I have read that McCarry spent a decade with the CIA.
