A: Gerry Standing (Dennis Waterman), Jack Halford (James Bolam) and Brian Lane (Alun Armstrong) have for a variety of reasons handed over their badges and accepted premature retirement.
But their hunger to right the wrongs of the past is still strong, and they're willing to resort to the most unconventional methods if it means they can close a case.
Producer Tom Sherry, who's also worked on Murphy's Law and Burn It, says: "Each episode goes into a different world – from greyhound racing to celebrity chefs to the moving story of an Asian girl who has been in a coma for eight years.
"Some are dark, others are more frivolous – our team is sent to interview a record carp and dig up a dead dog as well as interrogate murderers and interview victims – but in each one, their rule-breaking attitude brings about an interesting result."
"It's a delight to work with four leading actors who bring a wealth of talent and experience to the screen.
"Alun, James, Amanda and Dennis have made the roles in New Tricks their own and I'm sure their credibility, together with strong writing, is what has attracted such a high calibre of British actors as guest stars."
