The longer he stayed in this room, the more suspicious Adam was not just of the shop and its owners but of everything. Why did that woman know the door was mahogany, as opposed to any other type of wood? Why did the blond who'd pushed on it say something about a key, as though it was a guarantee that there would be one available in the room and that it would be the easiest, simplest option?

He didn't want to voice his concerns and panic everyone, but he did think something was definitely fishy about this. Edging his way back to the door they'd come in through, Adam tested it and found that it was locked. Without alerting anyone else to this news, he slipped his wand out and muttered "Alohomora," under his breath, which produced a mechanical clicking sound but did not open the door.

Magically locked, then. Great.
