The Doctor left the squad car parked on Fifth Avenue, and Amy took a moment to take in the beauty and sheer scale of Central Park. Above her, ducks circled lazily, and thousands of lights were being switched on across the city, making the steel and glass towers glow against the sky. 'Wow!' Amy was impressed. 'On the maps, the park looks tiny. But you could fit all of Leadworth into it. Twice.' The Doctor signalled for Amy to be quiet as they got within sight of the Zoo. As the evening drew in, the Zoo was shutting down for the night, and the main entrance was full of groups of schoolchildren, filing out as the security guards closed up. 73 DOCTOR WHO 'Where exactly is the Zoo?' the Doctor asked. Before Amy could speak, he answered his own question. 'It's right in the middle of New York, isn't it...' 'Does that mean anything?' Amy asked. 'We're about to find out.' They circled the Zoo fence until they reached the service gates. Beyond the heavy steel doors, they could see the top of the large animal enclosure, tantalisingly close.
