Yesterday (22 Feb 2017) I was watching Drama channel and it was New Tricks Series 9 episode 1
www.imdb.com/title/tt2128043/
"The team is less than pleased when arrogant civil servant Stephen Fisher coerces them into investigating the murder - in 1851 - of Abigail Padua, a mathematical expert whose death led to the collapse of her family business and a widespread financial crisis. With no living witnesses and a different geography to the time the team must pore over the original statements to prove that the killer was a witness who lied to the police."
Anyway, I fell asleep and missed the ending. Who killed Abigail and why did Stephen Fisher want to find out!
Many thanks (I cannot find the answer on line!), no worries if I get no replies....
