M ilgrim had never liked the City. It had always seemed too monolithic, though to some older scale of monolith. Too few hiding places. A lack of spaces in between. It had been turning its back on people like himself for centuries, and made him feel like a rat running along a baseboard devoid of holes. He felt that now, very strongly, though they weren’t running. Walking, but briskly, owing to Heidi’s long legs.
