Dom steps inside Glasgow’s Britannia Panopticon, the world’s oldest surviving music hall, to help piano technician Jamie revive Henrietta, a 1904 Nilson pianola with roots in a New York speakeasy. Will is in Inverness to collect Debbi’s handcrafted chess set, a family heirloom that requires Kirsten’s expert touch if it is to be played with again. In Birnam, Dom is getting hands on with a craft that has remained unchanged for centuries as he masters steam-bending and pine-tar finishing with Scotland’s only wooden ski maker.
