The Mysterious Room 45 (Pokemon x Detective)

The Mosey Hotel is a well known hot spot for many Pokemon trainers to visit at least once in their life time. But is there something infamous about room 45? For the past 2 years room 45 has been blocked off from any reservation since the "noises" began. Anyone who caught trying to break into room 45 is immediately detained and sent to the "management office" where things become blurry.
