Charlotte joined the Metropolitan Police in London at the age of 19 and, after a short while, became a Detective Constable. She spent 20 years in the Police and her last 10 years specialised in serious crime squads, including the Flying Squad and the Regional Crime Squad, investigating crimes such as armed robberies, kidnappings, and drug importation.

A holiday in New Zealand in April 1999 led to Charlotte moving to NZ, initially for a year, but she loved it so much she never returned to work in the UK. Instead, within 3 weeks of arriving, she had a job as an investigator with the Serious Fraud Office.

This background in Law Enforcement led Charlotte to become a Licensed Private Investigator.
