The same was true for the stranger in the tiny town of Amesville, Connecticut, who woke at Eva Bates’s house a little before six o’clock, slung her bag on her shoulder, and rejoined the Appalachian Trail. Emma walked until she came to a low, swampy stretch in the woods, where the mosquitoes rose from the earth in thick clouds. She slapped at them a few times and then hurried to higher ground, where she stopped to thin them out.
