Ep 8. Blue Flower

The detectives investigate the murder of an East German immigrant, but all they have to go on are his mysterious final words, which translate as `blue flower'. As they piece together his remarkable story, Sandra tries to gain the trust of his estranged daughter. A chance meeting with a woman whose son was killed in a road accident nearby sends the detectives in the right direction - to a recycling plant where Max had been employed to sort waste paper. It turns out that prior to the demolition of the Berlin Wall, he had connections with the Stasi, but what's not clear is whether he was working for them - or against them.
