In London the Jackal spent the last fortnight of June and the first two weeks of July in carefully controlled and planned activity. From the day of his return he set himself among other things to acquire and read almost every word written about or by Charles de Gaulle. By the simple expedient of going to the local lending library and looking up the entry for the French President in the Encyclopaedia Britannica, he found at the end of the entry a comprehensive list of reference books about his subject.
After that he wrote off to various well-known bookshops, using a false name and a forwarding address in Praed Street, Paddington, and acquired the necessary reference books by post. These he scoured until the small hours each morning in his flat, building up in his mind a most detailed picture of the incumbent of the Elysee Palace from his boyhood until the time of reading. Much of the information he gleaned was of no practical use, but here and there a quirk or character trait would emerge that he noted in a small exercise book. Most instructive concerning the character of the French President was the volume of the General's memoirs, The Edge of the Sword (Le Fil de I'Epee) in which Charles de Gaulle was at his most illuminating about his own personal attitude to life, his country and his destiny as he saw it.
The Jackal was neither a slow nor stupid man. He read voraciously and planned meticulously, and possessed the faculty to store in his mind an enormous amount of factual information on the off-chance that he might later have a use for it.
But although his reading of the works of Charles de Gaulle, and the books about him by the men who knew him best, provided a full picture of a proud and disdainful President of France, it still did not solve the main question that had been baffling him since he accepted in Rodin's bedroom in Vienna on June 15th the assignment to go through with the assassination. By the end of the first week in July be had still not worked out the answer to this question-when, where and how should the «hit' take place? As a last resort he went down to the reading room of the British Museum and, after signing his application for permission to research with his habitual false name, started to work his way through the back copies of France's leading daffy newspaper Le Figaro.
Just when the answer came to him is not exactly known, but it is fair to presume it was within three days from July 7th. Within those three days, starting with the germ of an idea triggered by a columnist writing in 1962, cross-checking back through the files covering every year of De Gaulle's presidency since 1945, the assassin managed to answer his own question. He decided within that time precisely on what day, come illness or bad weather, totally regardless of any considerations of personal danger, Charles de Gaulle would stand up publicly and show himself. From that point on, the Jackal's preparations moved out of the research stage and into that of practical planning.
'It took long hours of thought, lying on his back in his flat staring up at the team-painted ceiling and chain-smoking his habitual king size filter cigarettes, before the last detail had clicked into place.
At least a dozen ideas were considered and rejected before he finally hit on the plan he decided to adopt, the «how' that had to be added to the «when' and «where' that he had already decided.
The jackal was perfectly aware that in 1963 General de Gaulle was not only the President of France; he was also the most closely and skilfully guarded figure in the Western world. To assassinate him, as was later proved, was considerably more difficult than to kill President John F. Kennedy of the United States. Although the English killer did not know it, French security experts who had through American courtesy been given an opportunity to study the precautions taken to guard the life of President Kennedy had returned somewhat disdainful of those precautions as exercised by the American Secret Service. The French experts' rejection of the American methods was later justified when in November 1963 John Kennedy was killed in Dallas by a half-crazed and security-slack amateur while Charles de Gaulle lived on, to retire in peace and eventually to die in his own home.
What the jackal did know was that the security men he was up against were at least among the best in the world, that the whole security apparatus around De Gaulle was in a state of permanent forewarning of the likelihood of some attempt being made on their charge's life, and that the organisation for which he worked was riddled with security leaks. On the credit side he could reasonably bank on his own anonymity, and on the choleric refusal of his victim to co-operate with his own security forces. On the chosen day, the pride, the stubbornness and the absolute contempt for personal danger of the French President would force him to come out into the open for a few seconds no matter what the risks involved.
The SAS airliner from Kastrup, Copenhagen, made one last swing into line in front of the terminal building at London, trundled forward a few feet and halted. The engines whined on for a few seconds, then they also died away. Within a few minutes the steps where wheeled up and the passengers started to file out and down,. nodding a last goodbye to the smiling stewardess at the top. On the observation terrace the blond man slipped his dark glasses upwards on to his forehead and applied his eyes to a pair of binoculars. The file of passengers coming down the steps was the sixth that morning to be subjected to this kind of scrutiny, but as the terrace was crowded in the warm sunshine with people waiting for arriving passengers and trying to spot them as soon as they emerged from their aircraft, the watcher's behaviour aroused no interest.
As the eighth passenger emerged into the light and straightened up, the man on the terrace tensed slightly and followed the new arrival down the steps. The passenger from Denmark was a priest or pastor, in a clerical grey suit with a dog collar. He appeared to be in his late forties from the iron-grey hair cut at medium length that was brushed back from the forehead, but the face was more youthful. He was a tall man with wide shoulders and he looked physically fit. He had approximately the same build as the man who watched him from the terrace above.
As the passengers filed into the arrivals lounge for passport and Customs clearance, the Jackal dropped the binoculars into the leather briefcase by his side, closed it and walked quietly back through the glass doors and down into the main hall. Fifteen minutes later the Danish pastor emerged from the Customs hall holding a grip and a suitcase. There appeared to be nobody to meet him, and his first call was made to the Barclays Bank counter to change money.
From what he told the Danish police when they interrogated him six weeks later he did not notice the blond young Englishman standing beside him at the counter apparently waiting his turn in the queue but quietly examining the features of the Dane from behind dark glasses. At least he had no memory of such a man.
But when he came out of the main hall to board the BEA coach to the Cromwell Road terminal the Englishman was a few paces behind him holding his briefcase, and they must have travelled into London on the same coach.
At the terminal the Dane had to wait a few minutes while his suitcase was unloaded from the luggage trailer behind the coach, then make his way past the checking-in counters to the exit sign marked with an arrow and the international word «Taxis'. While he did so the Jackal strode round the back of the coach and across the floor of the coach-park to where he had left his car in the staff car-park. He hefted the briefcase into the passenger seat of the open sports model, climbed in and started up, bringing the car to a halt close to the left-hand wall of the terminal from where he could glance to the right down the long line of waiting taxis under the pillared arcade. The lone climbed into the third taxi, which cruised off into the Cromwell Road, heading towards Knightsbridge. The sports car followed.
