OK here's the deal folks - I see night is in 8 hours time or so and I won't be back on. My vote stays with Ogre (I feel unfortunately that the timezone difference is not helping but that's unavoidable at this early stage).
My suspects in order :
Ogre (voted for)
DD
I'm naming a third because I think we all should, with zombie turns about to be visited upon us, so that the survivor townies have something to measure as regards past behaviour. My third suspect is Lady G - weaker than the other two, which are also pretty weak.
