Tension mounts as Ned and Sasha are forced to work together when the body of a film critic found in a sewer is thought to be linked to the 20-year-old cuddle of a concept artist. As the team interviews the victim's contemporaries, groupies and assistants, looking for possible connections between the passings, the members find themselves immersed in the macabre world of the occult. Griffin's expert knowledge of the history of London and in particular the hidden Fleet River, proves invaluable.
New Tricks follows the work of the Metropolitan Police Service's Unsolved Crime and Open Case Squad (UCOS). Led by Detective Superintendent Sandra Pullman, it is made up of retired police officers who have been recruited to reinvestigate unsolved crimes.
The series title is taken from the popular expression "You can't teach an old dog new tricks". The "old dogs" are successful in adapting their skills and experience to modern policing, with their knowledge of past cases proving especially useful.
