Test your skills of deduction with the October 2021 edition of Riddle Me This: Haunted Hotel
Alan and Bob are staying in two different rooms in the same hotel. Alan has a valuable ring that he wants to give to Bob, but the hotel is haunted with ghosts lurking around the hotel, trying to find and hurt both Alan and Bob. Because of this, neither of them are able to safely leave their room. The only way they are able to transfer items to and from each other is with the help of the bellhops that work at the hotel. Alan and Bob each have a small portable safe that can be secured with multiple locks, and Alan and Bob also each have a padlock and corresponding key. Unfortunately, the bellhops cannot be trusted and will steal anything and everything that is inside the safes if they are unlocked.
