How did the killer enter?
Hint 1 of 16:
Well, there was no forced entry on the door.
Hint 2 of 16:
And the stairs are incredibly creaky, so no one could have crept up them
without someone knowing.
Hint 3 of 16:
So maybe they didn't get into Robner's room via conventional methods.
Hint 4 of 16:
Really, the other possible entryway is pretty obvious.
Hint 5 of 16:
Check out the rug in Robner's room.
Hint 6 of 16:
Mud, huh? Maybe the killer had their shoes in some mud.
Hint 7 of 16:
Now look at the balcony.
Hint 8 of 16:
Look at the railings.
Hint 9 of 16:
Scratch marks! So, someone must've climbed up!
Hint 10 of 16:
There's some more evidence to be found, though.
