Art & Apparitions

Sazzy's latest client is a ghost. Not just any ghost, but that of the legendary dancer, Mischiel Wingedfoot, twin to Kimeriel Magictouch, the second most famous painter in Conyor Ness' history.
Mischiel wants Sazzy to find out what happened to her brother Kimeriel. Did he walk into his painting or was he pushed, and, in either case, why didn't he just walk back out again?
Not that Sazzy can suddenly see and hear ghosts, but her client's representative can.
Sazzy wants to say no, but the Youngest Sinister Fate expects her to take th case. So, she can hardly refuse.
But where to start? And how much is she going to be able to find out about a 525 year old cold case?
