The address of the Embassy of the Islamic Republic of Pakistan was Avenue Delleur 57, 1170 Watermael-Boitsfort, and they saw that it would be open for business in the afternoon between three and four o'clock. They decided to go to the consular section and enquire about tourist visas and also try to find out if there was a scientific attaché at the embassy, in the hope they could deal with him without having to go to Pakistan. They agreed not to divulge the fact that the information they had would put them in the Pakistani national pantheon — if such a thing existed — side by side with AQ Khan, Zulfikar Ali Bhutto and Abdus Salam the (only) Pakistani Nobel laureate in physics.
Greg called David immediately and reported the conversation that he had with Ammer. He added that his people had put a tap on Ammer's phone so he also had a recording of the call and would receive a copy shortly. David said he would come over to listen to the recording. By the time he arrived at Greg's office the recordings of both calls were ready. First, they were convinced that Ammer had given Greg a full report of Nagib's call and did not try to hide any information or even hint that he had suffered a traumatic visit. They also realized that Nagib was suspicious that Ammer may not be acting in his best interests and did not trust him. However, the most interesting part was the recording of the siren that the analysts said was indeed similar to that of the Belgian police cars, probably Opel Astra or Opel Vectra, but also similar to that of first responders in other European countries, so it wasn't conclusively in Belgium but did provide a clue. David said that this supported their supposition that Nagib and Alia would try to leave Germany and get undercover in a big city that has a large Muslim community. They searched Google Earth maps and the closest place that fit this description was Brussels. This could also explain the type of siren they heard in the background. Greg tried to put a trace on the phone from which Nagib had called but there was no active signal as it was shut off. However, the record showed that the phone had last been used somewhere in near Brussels center.
David knew that the Americans were very anxious to catch Nagib and recover the classified information before it was distributed to enemies of the United States. What was conceived as a even a greater threat to national security was what would happen if the press and media became aware that this highly sensitive and classified information had leaked out from one of the most well guarded National Laboratories. Furthermore, to add insult to injury, that this was done by a person whose access to such material should never have been permitted. David heard Greg referring to Nagib as "the dreadful renegade" when he talked to Eugene and when he enquired about this Greg told him that it was the codename given to Nagib whose actions were obviously dreadful and he was considered as a renegade because he betrayed the country that gave him an education, a job and a much better life than he could have possibly dreamed of in his home country. He added that this avoided mentioning his true name in the internal communications to help limit the number of people who knew Nagib and what he had done.
David offered to help Greg in the search for the couple, but Greg said that he had no jurisdiction in Belgium and would have to hand over the case to the CIA station chief in Brussels. David said that Mossad had a strong presence in Brussels as it was the seat of several institutions of the European Community and also to counteract the operations conducted by the Arab states and their supporters. These operations were not limited attacks on Israeli officials and tourists but also to attempts against the local Jewish community, like the 2014 shooting and murder at the Jewish Museum by a French jihadist. Greg said that he appreciated the offer and will introduce David to Herb Harden, the CIA station head in Brussels. David thanked Greg and wished him a successful career with the hope that the fact that the couple was not apprehended while in Frankfurt would not end it prematurely. Greg sighed and said that if they were caught and the classified data retrieved then everybody would try to sweep the whole affair under the rug, but if the media got hold of the story then scapegoats would have be sought, found and sacrificed and he feared that he was on the short list.
David called the Mossad chief and brought Shimony up to date on the affair. Shimony told him to leave Frankfurt and focus on locating Nagib. David asked about the mission he had been assigned to concerning the Jewish community in Frankfurt that got him there in the first place and Shimony directed him to forget it as someone else would be sent from Tel-Aviv to take over the job. He promised David full support from all Mossad agents in Europe and told him he would become a national hero, albeit only among the top leaders of the intelligence and security communities, if he could quietly obtain a copy of the information that would be considered as a national treasure in Israel. David said that he would be on his way to Brussels immediately and expected to arrive there in the early evening and asked Shimony to instruct all available Mossad agents to gather at one of the safe houses in Brussels for a 10 pm meeting and briefing.
Nagib and Alia took the metro train from Gare Centrale to Herrmann-Debroux station that was the last stop of Line 5 and then the short #94 tram ride towards Louise getting off at Boitsfort Gare that was very close to the Embassy of the Islamic Republic of Pakistan. As they exited the station and approached it on foot they did not encounter any other tourists, and there appeared to be only a few Pakistanis who had business at the embassy. They were stopped first by the Belgian policeman outside the building who just asked them for some ID and when they showed him their US passports they were allowed to continue. Then they were asked to pass through a metal detector portal by the Pakistani security officer who also looked at their passports before waving them through to the receptionist. When asked what business they had at the embassy they said that they were considering a visit to Pakistan and Nagib added that he wanted to find out more about the level of chemical sciences there. The receptionist picked up the phone, muttered something in Urdu and referred them to the person in charge of public relations. A young woman dressed in a traditional shalwar kameez with embroidery on the front politely invited them to take a seat. Nagib was quite impressed by her good looks and lithe body that could be imagined beneath the colorful clothes. In lilting English she said that her name was Junaid and asked how she could be of assistance. They repeated that they were curious about Pakistan. Junaid looked at their names in their passports and asked if they were Muslims, and both said that they were, but added that they did not practice the religion, and expected their visit to Pakistan to change that attitude. Junaid asked Nagib and Alia what kind of jobs they held in the US and they answered that both were in government service until they recently quit, and that he was an analytical chemist and she was a secretary, refraining from mentioning Los Alamos National Laboratory. Junaid who was in fact an agent of the Pakistan Intelligence Community (PIC) perceived that they were not completely forthcoming and when she saw that their home address was listed as Los Alamos, New Mexico, she decided to call the scientific attaché who was the senior member of PIC at the embassy. She asked Nagib and Alia if they wanted some refreshment and when they said they would like mint tea she excused herself and went to arrange the refreshment and also call the attaché. Before returning with the tea she quickly gave him an update on the unusual couple that sauntered into the embassy. She introduced the scientific attaché as Rahman Chenna and he told the couple that one of his responsibilities was to collect scientific data related to advanced projects that may be beneficial to Pakistan. At that stage Nagib felt that the conversation was being conducted with both sides revealing a little information and hiding a lot more, and again thought of how porcupines made love — very carefully.
