Grant's Labyrinth

"(...) They might be in Aubrey's room. But he did not know where that was. The more he explored this place, the more corridors and seating spaces and ramps he discovered, and in his wanderings he was still apt to get lost. He would take a certain picture or a chair as a landmark, and the next week whatever he had chosen seemed to have been placed somewhere else. He didn't like to mention this to Kristy, lest she think he was suffering some mental dislocations of his own. He supposed this constant change and rearranging might be for the sake of the residents- to make their daily
exercise more interesting."
