Possible break through.
Last night I was researching the history of the manor, and found out that guy in charge of building this place... Lucifuge went missing just before he completed the house.
They couldn't find his body. There is his grave near the south lawn, but there is no body under it.

Perhaps we could end the curse if we can find his body and give it a proper burial.

We still don't know how the clock and the girl is related to all this. So I'll keep searching.

As for Captain Blackadder. Give him one more night. Apparently someone must die everynight anyway.
