An Attack of Spirits

From: Detective
Description: All the evidence we found shows that there was a struggle in the bedroom, but who was the Mistress fighting so desperately against? Martha told me of a simple ritual - if we gather all the evidence together and surround it with City artifacts, then we can see what happened in the bedroom.
Completed: Woah! As soon as we performed the ritual, these silhouettes came alive in the bedroom mirror. The Mistress is surrounded by the ghosts of men; she's scared and trying to escape. I can tell we're hot on the trail of a secret, I'll be a detective yet!
