Olivia applied mosquito repellent and squatted in the woods for two hours, then walked uphill to a little road and then down the road for a kilometer to a place where hundreds of people, mostly young women, were streaming out of a huge new apartment complex to a bus stop. Like them, she took a bus to the ferry terminal, and from there she joined in a flow of thousands across the wide aluminum gangplanks onto a crammed passenger ferry. An hour later she was in downtown Xiamen. Following instructions memorized from that envelope, she went to a FedEx office and picked up a large box that was waiting for her. Slitting it open with a penknife from her purse, she found that it contained an altogether typical-looking rollaway suitcase of the type currently making the rounds of every airport luggage carousel in the world.
