Our History

Line of Inquiry was established in 2020 by expert investigator, Gavin Burrows, a private investigator since 1994 and highly experienced lawyer, Nicholas Croft LLB, who has been in practice since 1981. Gavin and Nicholas have a history of successful collaboration dating back to 2007 and decided to combine their years of international experience into a full-service investigation business aimed at elevating the standard services that were available at the time. Anne-Marie Harris, former Ministry of Justice Executive Officer since 2001, joined the team as a Senior Partner and brings valuable experience with her.
