The stairs ran round the lift shaft, and at each curve on the rear of the building the stairs halted to make room for a small half-landing. On each second floor this landing gave access through a door in the rear wall of the block to a steel fire-escape. At the sixth and top floor, apart from the attics, he opened the rear door and looked down. The fire-escape led to an inner courtyard, around which were the rear entrances to the other blocks that made up the corner of the square behind him. On the far side of the courtyard the hollow square of buildings was penetrated by a narrow covered alleyway leading towards the north.
The jackal closed the door quietly, replaced the safety bar, and mounted the last half-flight to the sixth floor. From here, at the end of the passage, a humbler staircase led to the upper attics. There were two doors in the passage giving access to flats overlooking the inner courtyard and two others for flats on the front of the building. His sense of direction told him either of these front flats contained windows looking down into the Rue de Rennes, or half-sideways on to the square and beyond it the forecourt of the station. These were the windows he had been observing for so long from the street below.
One of the name plates next to the bell pushes of the two front flats he now confronted bore the inscription «Mlle Beranger'. The other bore the name «M. et Mme. Charrier'. He listened for a moment but there was no sound from either of the flats. He examined the locks; both were embedded in the woodwork, which was thick and strong. The tongues of the locks on the far side were probably of the flock bar of steel type so favoured by the security conscious French, and of the double-locking variety. He would need keys, he realised, of which Mme Berthe would certainly have one for each flat somewhere in her little loge.
A few minutes later he was running lightly down the stairs the way he had come. He had been in the block less than five minutes. The concierge was back. He caught a glimpse of her through the frosted glass pane in the door of her cubbyhole, then he had turned and was striding out of the arched entrance.
He turned left up the Rue de Rennes, passed two other blocks of apartments, then the facade of a post office. At the corner of the block was a narrow street, the Rue Littre. He turned into it, still following the wall of the post office. Where the building ended there was a narrow covered alleyway. The Jackal stopped to light a cigarette, and while the flame flickered glanced sideways down the alley. It gave access to a rear entrance into the post office for the telephone exchange switchboard night staff. At the end of the tunnel was a sunlit courtyard. On the far side he could make out in the shadows the last rungs of the fire-escape of the building he had just left. The assassin took a long draw on his cigarette and walked on: He had found his escape route.
At the end of the Rue Littre he turned left again into the Rue de Vaugirard and walked back to where it joined the Boulevard de Montparnasse. He had reached the corner and was looking up and down the main street for a free taxi, when a police motor-cyclist swept into the road junction, jerked his machine on to its stand, and in the centre of the junction began to halt the traffic. By shrill blasts on his whistle he stopped all the traffic coming out of the Rue de Vaugirard, as well as that heading down the Boulevard from the direction of the station. The cars coming up the Boulevard from Duroc were imperiously waved into the right-hand side of the road. He had barely got them all stopped when the distant wail of police sirens was heard from the direction of Duroc. Standing on the corner looking down the length of the Boulevard de Montparnasse, the Jackal saw five hundred yards away a motorcade sweep into the Duroc junction from the Boulevard des Invalides and start to head inwards him.
In the lead were two black-leather-clad motards, white helmets gleaming in the sun, sirens blaring. Behind them appeared the sharklike snouts of two Citroen DS 19s in line astern. The policeman in front of the jackal stood bolt upright facing away from him, left arm gesturing rigidly down towards the Avenue du Maine on the southern side of the junction, right arm bent across the chest, palm downwards, indicating priority passage for the approaching motorcade.
Heeling over to the right, the two motards swept into the Avenue du Maine, followed by the limousines. In the back of the first one, sitting upright behind the driver and the ADC, staring rigidly in front of himself, was a tall figure in a charcoal-grey suit. The Jackal had a fleeting glimpse of the uptilted head and the unmistakable nose before the convoy was gone. The next time I see your face, he silently told the departed image, it will be in closer focus through a telescopic sight. Then he found a taxi and was taken back to his hotel.
