Found this series ten days ago and am now half way through Series 6 (in addition to PT job and PT teenage child) - I am OBSESSED. Having dreams about the cast. Fantasising about Patrick. Huge crush on Zara and Billie. Crying over every death and drama. Shouting at the TV. I've now invested over 50 hours in it. And am deeply ashamed. And have no one to discuss it with 
Anyone else? Please?!!
