across Poland, Czechoslovakia, and East Germany. In 1962 he vis-
ited Japan and India, and the following yeardefectedin London
while on an approved visit, accompanied by the usual contingent of
KGB escorts. He arrived on 4 September and while staying at a hotel
in Bayswater he declared his decision not to return home to an En-
glish acquaintance, who in turn contacted the Security Service. MI5
kept him under discreet surveillance and ensured his plan to elude
the KGB went off unhindered.
After his defection in London, Krotkov continued to write and in
1967 publishedThe Angry Exile, a critique of postwar social condi-
tions in Moscow. Two years later he gave evidence to the U.S. Senate
Committee on Judiciary under the name ‘‘George Karlin’’ and in
1979 publishedRed Monarch, a semisatirical biography of Stalin.
Krotkov was allowed to settle in the United States but was never ac-
cepted as an authentic defector, and he eventually died in Spain.KUCZYNSKI, JURGEN.A lifelong Communist, Professor Jurgen
Kuczynski came to Britain, where his father was an Oxford aca-
demic, as a refugee before World War II. He was approached by
Klaus Fuchs in 1941 to put him in touch with Soviet intelligence.
This he had done by visiting the Soviet embassy and seeingSimon
Kremer, ostensibly a secretary but actually theGRU’s Londonrezi-
dent. A leading member of the German anti-Nazi expatriate commu-
nity in England, Kuczynski had been employed during the war by the
U.S. Army Air Force Bombing Survey. Immediately after the war he
performed the same service for Fuchs, who had returned to London
from Los Alamos, and then settled in East Berlin. It was not until
some years later that he learned the GRU contact assigned to handle
Fuchs in 1941 had been his sister,Ursula Beurton, although he was
not allowed to mention the fact in hisMemoirs, published in 1983.
