Geoffrey Wilson joined the Hong Kong Police in 1933. In 1936 he married Joy Noel Harris-Walker.
He was chosen to be part of 'Z' Force, a special operations unit which would work behind Japanese lines after an attack, but had to withdraw after it became clear this was incompatible with police duties during an invasion.
He was interned in Stanley, and in 1943 was involved with communicating with the British Army Aid Group in the organisation of an escape which never took place.
After the war he became Commissioner of Police in Sarawak (1953-1958) and Tangangyika (Tanzania, 1958-1962). He was appointed CMG in 1961. He retired to Portugal.
