[X] Use Retrocognition on Monford's Solar, out of personal curiosity if nothing else. Meanwhile Dany will use Soulseeker targeted on the dead maid. -[X] Also cast Vision (times as necessary, estimated CL is 26 with buffs) on the gathered poison - -[X] Where was it created? -[X] Who died by it before? --[X] Use your Psionic Gloves of Object Reading to examine the sample. -[X] Have the Faceless Men consulted to see if not only this poison is ringing a bell, where it could be acquired, but generally also the mindset of an assassin. This one seems to be acting subtly, but they are also moving in and around private and guarded areas, so they have some capability in mundane wetwork or magic, or both. -[X] If they would be bold enough to attack Monford, arranging a clandestine meeting where they can be counter ambushed might be preferable, but if they will only move once they leave all trace of their presence erased, every attack on Monford might be conducted on a pre-arranged basis, or with at least a large enough gap. --[X] A better question would be perhaps what would tempt the assassin into a compromised position if they never conduct a killing face to face.
