Murder at the Excelsior Hotel

I have answers.
Room 225. Tonight. Come alone.
They're watching.
Reports of strange occurrences have been circulating around Arkham about the prestigious Excelsior Hotel: disappearances, bizarre sightings, sudden closures that go on for days without warning. You tried talking to the police about these suspicious claims, but they dismissed you with little more than a glance up from their desks. So, when you receive a note promising answers if you come to the mysterious location, you feel compelled to make the meeting.
