So Hermione just followed her instincts, drifting towards a rotted and derelict sort of jetty a short way along the road once she’d left the Muggle Port of Calais. There was no particular reason to head in this direction rather than any other, but Hermione did feel a sort of pull towards the forgotten pier, in the same way that tourists were fascinated by ancient tombs or megalithic monuments. Maybe this had the same mystic power as one of those.
