The Woolcott family has owned and operated their shop for three generations.
The current shop is located at a quiet intersection at the edge of town, and certainly does not have a secret underground passage to any brick outbuildings.
The outlandish rumours about the shop and its proprietors are, of course, only rumours and hearsay.
Mind you, if one were to find oneself on desperate trouble, without hope of rescue or remedy, and if one were to drop a note about said trouble on the floor of the shop ... Well, who knows what might happen?
Entirely by coincidence, of course.
