distorted time

Exploration Stage: Postal Dovecote
From: Kira Woodville
Description: Among the items the doves have stolen from the perpetrator's hideout is an important clue that leads to the identity of the perpetrator. What I find curious is the strange hourglass. There is something...wrong with it. What do you think?
Completed: Yes, it is. The sand in this hourglass flows from bottom to top. It seems the killer knows how to manipulate time. Hmm... I have heard information about a similar person from a colleague in Lower City.
