BARCLAY, SIR COLVILLE• 33donated for wartime use by RF Section); and Berkeley Court,
Glenworth Street.BALLOON.Code name for Dickie Metcalfe, adouble agentrun by
MI5during the World War II as part oftricycle’s network. Met-
calfe had resigned his commission before the war and portrayed him-
self as an embittered ex-soldier who had fallen into debt, a cover
story swallowed by theAbwehr.
BALLYGUNGE.Intelligence School ‘‘C,’’ located in the Calcutta sub-
urb of Ballygunge, wasGCHQ’s regional headquarters in India dur-
ing World War II. Concentrating on interceptedJapanesesignal

BANKNOTES.Tracing the history of individual banknotes can be a
useful investigative skill, andMI5has liaised closely with the Bank
of England to monitor the movement of cash. This resource was dis-
closed in 1920 when the foreign secretary, Lord Curzon, revealed
that banknotes found in the possession of a Sikh agitator searched on
the Indian frontier had been traced to a joint account in London held
in the names of Leonid Krassin and the secretary of theSoviet Trade
Delegation, Nikolai Klishko.
In September 1939, £1,000 in Sterling removed from a safe be-
longing to Helen Wilky was examined and found to have been han-
dled by the Moscow Narodny Bank and transferred to Rotterdamsche
Bankverengigen in Amsterdam, where Paul Hardt had passed it to an
account in the name ofHenri Pieck. As Wilky was CaptainJohn
King’s mistress and he had given her the money, this continuity of
evidence showed a payment from a Soviet spy to an intermediary,
ending up with King.
Similarly, in June 1940 Mathilde Krafft was identified as the
source of banknotes mailed anonymously to MI5’sdouble agentAr-
thur Owens, codenamedsnow. On that occasion the cash had been
traced by MI5’s banking expert, Sir Edward Reid, to the Selfridge’s
department store, where a record of a purchase made by Krafft had
been retained.
