On one occasion, he used a modified watch to record his targets' conversations. He had many romantic and sexual relationships with his targets, including one that lasted six years.
His targets were unaware that he was married and had children under his real identity. He was identified because:
- One day, his long-term partner found his real passport under the name “Mark Kennedy,” as well as emails indicating that he had children.

- Electoral records for his birth year did not include an entry for “Mark Stone” but did include an entry for a “Mark Kennedy” who was married.
- A genealogy website included an entry for a “Mark John Kennedy” who was listed as being married and having children.
- The birth certificate of the son of “Mark Kennedy” listed the father's occupation as police officer.

On many occasions, the police seemingly disrupted or prevented actions based on information he provided. On one occasion, he accused another activist of being an infiltrator. He had a sexual relationship with one of his targets.
He was identified because:
- He exhibited suspicious behavior. For example, in 2003, he requested to be named as a defendant in a civil court case against activists, presumably to gain access to their legal strategy. This was considered suspicious because activists would not normally want to be named as defendants as this would expose them to fines or other negative consequences.
- In 2004 or 2005, an activist revealed that a “well-placed contact within the security industry” had claimed that Gratwick was an infiltrator working for the security company Verify.
- In 2015, an activist learned that, in 2002, former infiltrator Jim Boyling had claimed that Gratwick was an infiltrator.
- In 2016, a company was founded at the address where the security company Verify had been based. The company listed two directors: Gratwick and the son of the founders of Verify.
