To paraphrase Tolstoy, all rich places were alike, but each poor place was poor in its own way. The slums of Lagos, Belfast, Port-au-Prince, and Los Angeles each would have presented a completely different and bewildering panoply of risks. But just from looking at this map, Sokolov knew that he could go to Gulangyu and walk its streets and make his way in the place just as well as he could in a parky suburb of Toronto or London.
