In those years before mobile phones, email and Skype, travelers depended on the rudimentary communications system known as the postcard. Other methods--the long-distance phone call, the telegram--were marked "For Emergency Use Only." So my parents waved me off into the unknown, and their news bulletins about me would have been restricted to "Yes, he's arrived safely,"and "Last time we heard he was in Oregon," and "We expect him back in a few weeks." I'm not saying this was necessarily better, let alone more character-forming; just that in my case it probably helped not to have my parents a button's touch away, spilling out anxieties and long-range weather forecasts, warning me against floods, epidemics and psychos who preyed on backpackers.

Going by Dr. Marriott's description, Zoe imagined it to be small and elegant as she peered into dozens of shelves, rummaging through the contents. There were globes and charts and atlases, pocket watches and hand-painted Indian silk, gold-plated cutlery, litter coffers of spice, inlaid combs, silver fasteners, trinket boxes, blown-glass figurines, turn-of-the-century postcards with foreign stamps, and portraits of Victorian authors in elaborate frames. But nowhere did she discover a stone of any kind, with or without runes.
