1891 - East River Hotel Murder: Book 8 (Murder Mysteries of Old New York)

Hotels are tremendous places to capture energies of their occupants. Whether they are residing at the hotel on a long term basis or just passing through; the excitement, the heartbreak, the anticipation and the rage all get funneled through that one spot. The energies leave behind an imprint of those energies. The East River Hotel is no different. It's called home to one of the most gruesome murders and even long after the blood has been wiped clean, there is still a residue of what took place.
Maybe this is what happened.
