Anything can spark an idea. A casual remark from a spouse, the sign for a road, the scent of a stranger’s perfume that has been applied so thoroughly it lingers in the air minutes after they’ve passed. Away to another land, a pace beyond the street, or maybe to the final land. Perhaps their perfume is not just perfume, but a way for the organisation they work for to track them, figure out the exact code that unlocks the doors from world to world. Random or systematic. Like the mind.
