The city looked tired and disappointed, the Eiffel Tower fighting against a mass of heavy clouds. There was nobody sitting at the tables outside the cafes, and for once the little kiosks selling paintings and postcards were being ignored by the tourists, who were hurrying back to their hotels. It was five o'clock in the afternoon and the evening was drawing in, unnoticed. The shops and offices were emptying, but the city didn't care. It just wanted to be left alone. The helicopter had landed in a private area of Charles de Gaulle airport, and a car had been waiting to drive them in. Alex had said nothing during the flight and now he sat on his own in the back, watching the buildings flash by. They were following the Seine, moving surprisingly fast along a wide, two-lane road that dipped above and below the water level. Their route took them past Notre Dame. Then they turned off, weaving their way through a series of back streets with smaller restaurants and boutiques fighting for space on the pavements.
