Wales Hotel, second floor.
The hallway outside the crime scene room was crowded with people, all guests of the hotel.
Per Arthur's order, all guests were retained inside the hotel until the investigation of the crime scene was completed.
Policemen, who had arrived earlier, had already finished their inquiry work with all the individuals present; upon seeing Arthur's arrival, they handed their investigation records to their superior.
"Chief, here is the information collected so far for your review."
Arthur received the materials and instead of examining them immediately, he first glanced over the room's layout.
It was a relatively narrow, irregularly shaped room with simple furnishings: a bed barely big enough for two people to lie down normally, a nightstand for miscellaneous items with an extinguished gas lamp on it.
Opposite the door was a wooden skylight draped with black curtains, and beneath the window sat an iron canister, about two inches high.
