New Tricks ‘The Girl Who Lived’, GEM 20:00 Wed 11 May is a repeat, but it isn't flagged as one in the IceGuide.
It's the 4th episode of series 9 and was made in 2012. It was shown some time ago on Australian TV.
There are no new New Tricks. The show was wound up (along with UCOS) in S12 E10, `The Crazy Gang’.
