Very good. It's well known in the supernatural world for its harmful properties, the plant on its own is sometimes used in alchemical compounds or thaumaturgical rituals. Anyone with a sixth sense would be able to tell that one is different, however; it's the original one used to slay Baldr, something that by all rights should've been a priceless but lost magical artifact.

[A beat, and she gives a small shrug, because well, it's not so lost anymore, huh.]

Ironic that it was this, out of any and all mystical relics this manor's chosen to pick. It fits the murder theme, I suppose, and while I would've preferred something like Prometheus' Torch or Merlin's Diary, beggars can't be choosers, in our situation.
