Death and Dining

[Consistent Spontaneity]

Clues so far are:

~ (Known to Aura only)--Elias (host's grandson) knew about the plan beforehand somehow, and communicated it to Elisa (host's granddaughter). She got that from a seemingly innocent letter from Elias to "Jane" and has shown the letter to the others but not revealed the clue she gleaned from it.

~Elisa's doll collection is messed up and Aura is convinced it has something to do with Treachery, Sadness, and Betrayal.

~The following encoded conversation was found:
Elias:When is Aura coming?
Elisa:1730
Elias:We'll be gone by then.
Elisa:Leave clues. Where are they taking us?

~Mr. Gilfax's glasses were found--broken--in a dead attacker's pocket.

~This poem was carved into the side of Mr. Gilfax's bedroom wall:
Trouble is coming
But someone knew,
That the raven by the window,
Ate the clue...

From this clue they found the following poem-clue, in a different (same as the conversation) code, and also in German:

He who walks the pier by night,
And by day eludes all light.
She who reads but does not know,
who much abhors cooked snow
In ink unseen one more clue,
lies beneath an unclean shoe.

The first couplet has been agreed to code for Elias, but Elias himself does not know that.

~The dagger that struck Alex during Mark's interview was identified as Karin to have the blade of one of her original daggers (custom fit to her throwing style so not many people should be able to throw it accurately) and a new hilt: ivory with inlaid mother of pearl.
Two Rs have also been carved into the base of the blade. The only person in the contact book (with all of Mr. Gilfax's contacts in it) is a Richard Roland, whose name no one recognizes. Futher information on him is either unavailable or at present undisclosed.
In a container inside the dagger, in another code is the following poem:
he stranger's sign, death follows close,
Beware the eyes of the silvery ghost.
Change and turn to stay on course,
Or challenge the statue with knowledge's force.
Ignore the symbol carved on her head,
Suffer by the floating bed.

Notes on the attackers:
~They know a way out of the mansion. No one else does though, since telephone lines are cut and all automobiles inoperable. The entire estate is walled off by a tall hedge and any who try to climb it are sniped. Water and electricity works fine though.
~They wear masks that allow them suicide and prevent identification.
~They have voice-changers to prevent identification that way.
~They are armed and at random locations around the house but their main area of residence seems to be in basement and the southeastern area.
~~It has been mentioned that different parts of the house is built from different types of wood. Elias and Aura have revealed that they know about the structure pretty well, but others have indicated that they know about the secret passageways and layout/map of the mansion.
~They can navigate through the mansion's secret passageways.
~They do not have access to: The master bedroom (Mr. and Mrs. Gilfax's room), Elisa's room, Elias's room. It is unknown if they can access the guest rooms, library, infirmary, living room.
~Mark Jusung, the nephew of the Gilfax's gardener Mr. Charnel; (who's french) was caught as one of the schemer/kidnappers. He is currently with the rest of the group, staying with Alex, his love.
