However, it was his turn to surprised, for the woman's eyes immediately lit up and she fetched several bottles which she placed on the counter for Harry to inspect.

He was glad to get away with a mere twenty pounds and he beat a hasty retreat, clutching the precious bottle under his arm.

The curious bottle, which now adorns that bookcase in his study, was his first and last purchase of rare cosmetic.
