In June 1974 de Mowbray became concerned that evidence of So-
viet penetration of the Security Service was being overlooked and
decided to alert Prime MinisterHarold Wilson. His visit to Down-
ing Street, where he was received by theCabinet secretary, sparked
off the inquiry conducted by Lord Trend into the allegations made
againstSir Roger Hollis. At the conclusion of his investigation,
about which de Mowbray expressed severe reservations, Trend con-
cluded that ‘‘there was no compelling evidence against Hollis, or
even that MI5 had suffered hostile penetration.’’
De Mowbray retired in 1975 to start a new family in Kent and later
moved to West Africa. He helped editAnatoli Golitsyn’s bookNew
Lies for Oldand embarked on an ambitious project to record a com-
prehensive chronology of the Soviet Union. In the July/August 1984
edition ofEncounter, he contributed an article entitledSoviet Decep-
tion and the Onset of the Cold War.DEMPSTER, FERGIE.Born in August 1915 in Tangier, Morocco,
