Good luck,
Wilwa!
–And bad luck for us. Just when things were going well...
Now,
Greenie's death does
not look like a no-trace kill, as she'd attracted quite a bit of suspicion. So I think it's likely the wolves guessed her identity, and/or had a specific motive for killing her (framing someone, taking the heat off a wolf, double-bluffing, etc...)
EDIT:X'd with Zil.
