Although Aiwass had other places to temporarily hide, none was as good as the home of Bishop Mathers.
It was safe enough there, with no one coming to investigate; the living environment was also clean and comfortable, and Mrs. Mina would even provide meals—a craft at which she was quite adept, even by Aiwass's selective standards.
After all, Mrs. Mina hailed from the Iris Flower family. It was only logical that she could cook better than most Avalonians.
Most crucially, the place had easy access to a wealth of newspapers. At Sherlock's request, Mrs. Mina was now buying a pile of newspapers every day, not only the Glass Staircase Daily but also a plethora of tabloids.
According to Sherlock, even though those tabloids were filled with exaggerations and lies, they still held their value as references. They often contained news that the Glass Staircase Daily wouldn't report, and even a seemingly inconsequential sentence could hide important information.
