Gus joined Kent Constabulary in 1965. In 1970 he was posted to C11 at New Scotland Yard which led to a career based around drug trafficking
investigation and international money-laundering intelligence enquiries in the UK and across the globe. This included a secondment to the Independent Commission Against Corruption in Hong Kong
between 1982-1985.

On return he became the UK representative on the G7 Group of Countries, Financial Action Task Force. This culminated in a final posting to Rome in 1990 where he covered Italy and Albania. This included liaison with Judge Giovanni Falcone murdered by the mafia in Sicily in 1992. He was the first British police officer to be stationed in Italy and the only officer actually involved in investigating Italian organised crime (The Mafia).

Gus attained the rank of Detective Chief Inspector before retiring to work as a consultant researching similar activities in the UK and Europe.

In a departure from his previous life, after years of research, his book ‘Scott’s Forgotten Surgeon’ was published.
