Catriona (David Balfour) is the sequel to Kidnapped, and starts at the exact moment that Robert Louis Stevenson's more famous book ends - with Balfour in Edinburgh, standing cold and remorseful outside the offices of the British Linen Company. From there begins a rollicking series of adventures which sees our eponymous hero successively marooned on a remote island, traveling through Holland and France where he fights for his life with his old comrade Alan Breck, and finding time to fall in love with the spirited and beautiful Catriona, grand-daughter of the infamous 'Highland Rogue', Rob Roy.
