Percival Shacklehorn's socks

"I do apologise. My socks become a bit potent with all the effort of hunting —… I mean, observing the noble Graphorn."

- Percival Shacklehorn

Percival Shacklehorn owned a pair of smelly socks, which he kept in a locked suitcase in his tent. Mathilda Grimblehawk and her partner, following Healer Omar Abasi's advice that the sense of smell is connected to memory, used the odour from these socks to trigger the memory of Laura Thorn, reminding her of the beast that attacked her.

When asked about the socks, Percival Shacklehorn let it slip that he was illegally trying to hunt Graphorns in the Alps, instead of just studying them, as he had said before.
