A disused bus shelter in the market town of Sedbergh is a curious place for a quest to end, literary or otherwise. The town itself is rather curious too; geographically in Cumbria but on the wrong side of the M6 to be in the Lake District proper, it sits almost exactly on the watershed where the rolling green fells give way to the harsher limestone uplands of the Yorkshire Dales. Hard up against the Howgill Fells, it has always attracted walkers but in recent years it has also become a haven for readers. It now has seven bookshops, including an enormous second-hand one at the end of the High Street, and bookshelves are squeezed into any available space in the town’s other shops and cafés. When we arrived for cake and a potter while holidaying in Hawes, it was more in hope than expectation that here we would find the missing piece to complete the Scandinavian puzzle that our dining-room bookshelf had become.
