I've just been given the go ahead from my inside contact to release the names of 3 of the dead this Season. We should have the go-ahead to release the other 2 shortly, who are both females.
Update: 19th May - We now have all the deaths confirmed
I STRONGLY ADVISE YOU NOT TO READ THIS UNLESS YOU WANT TO BE TOTALLY SPOILED
The final death is one of the two women in the Looking Glass Station (Bonnie or Greta).
There are also a number of deaths of minor others that we don't really count.
