You were going to the store and, leaving your apartment, you noticed a masked man on the landing. He was looking in your direction, but did nothing - he just stood there and silently watched your door. You returned to the apartment and closed the door.

A couple of hours later, you finally decided to go out, having first examined the staircase through the peephole. After making sure that no one was around, you left the apartment and went to the store.

When you returned home, you found a note taped to your door. The note indicated the coordinates and time you had to arrive.
