Recent thriller set in Berlin, in English ?

I saw a movie, set in Berlin, but in English, with most of the cast spoke with British accents. (Though I didn't recognise any of them).

The main character was called David Glover, who worked for a courier/messenger company. He got caught up in a ploy by a female assassin called Lara / Lorca to kill off witnesses in a trial. Her trademark weapon was a crossbow.

The police think that the guy is the killer, and chase him and his girlfriend.

The film ends with a chase - the killer in a boat, the guy on a motorbike and the police in cars and a helicopter.

Anyone know this film - what's it called ?
