A lively and feisty young detective, Paula is not easily fazed. She never passes up the opportunity to take on more responsibility and is pleased to have another strong role model in Alex. She's not afraid to go undercover if an investigation demands it.

Detective Superintendent Kevin Geoffries

Mark Letheren
Kevin Geoffries has proved himself to be a worthy team member despite a few glitches along the way. While he wants to prove himself to Alex, he also respects Tony and believes that he can bring an extra needed dimension to the investigations.
