Gene Hunt:
No sign of Summers. Both of them put one man in the frame.

Alex Drake:
Lafferty. But how could he know that we'd brought Tomascz in?

Gene Hunt:
Someone in our station told him. Probably the same bastard that stole the note. Someone in CID. Someone on my team.

Alex Drake:
You thinking about Mac?

Gene Hunt:
I'm thinking about Mac, about Kevin Hales, about every investigation that's gone tits up for as far back as I can remember.
