extract Sahil Mazari from the apartment. Mazari worked as a computer network programmer at Deutsche BioMedizinische, assigned specifically to support DBM's distribution department. Mazari had been the only employee at DBM's Frankfurt facility flagged in the CIA database, which made him their most logical starting point. A Pakistani-born immigrant, he had taken several trips back to Pakistan within the past year, which raised red flags given his previous association with Al Qaeda extremists. The sudden, increased number of visits to Pakistan fit a pattern identified by the CIA. A dangerous precursor for escalated participation in extremist activity. Similar patterns had been identified prior to hundreds of attempted or completed terrorist attacks in the past.
Even more condemning, he had twice travelled back with known Al Qaeda extremists based out of Hamburg. Both of these suspected operatives had attended Technische Universität Hamburg-Harburg (TUHH) with Mazari, and one of them had even completed the same computer information technology degree. Dubbed "Terrorist U" by the CIA's Middle East analysts, former TUHH students could be found at the top of every "known terrorist" watch list around the world. A claim to fame that did not appear as a selling point on any of the university's marketing brochures.
Hamburg continued to serve as a hotbed of Muslim extremist activity, long after the infamous "Hamburg Cell" had changed the world on 9/11 under the leadership of Mohamed Atta. Atta had also been a "student" at TUHH, disappearing from Germany for extended periods of time to travel to Afghanistan. He continued his studies at leisure, while plotting the most diabolical terrorist attack in history. The CIA had no intention of letting any more TUHH "graduates" conduct attacks against the United States. Mazari's web of connections in Hamburg barred him from entering the United States and put him on a growing list of "likely terrorists."
Farrington approached the door marked 2F, and the rest of the team fanned out along the walls of the cramped stairway vestibule. Each apartment had its own small landing. Two old, rusted bicycles were stacked against the far wall, causing Petrovich to squeeze by to get behind Farrington. They all withdrew HK P2000 SK (subcompact) pistols from their waistline holsters and stood silent, taking in any noise from the apartment and stairway. Laughter vibrated from 2F. They would soon put an end to that.
Petrovich took a six-inch suppressor out of an inside pocket on his jacket and started screwing it onto the custom-threaded barrel. He would be first in the door, tasked with neutralizing any threat that stood in the way of abducting Mazari. They didn't have a wealth of information about his roommates, but couldn't discount the possibility that this could be a den of extremism.
Farrington tapped his right ear and nodded at Hubner, who quickly gave him a thumbs-up. Hubner was the only member of the group wearing an earpiece, connecting the assault group with the mobile surveillance team. Luke and his group were scanning local police channels, searching for any indication that the team might have unwelcome visitors. Apparently, the police channels were still clear. Farrington pointed at the door, which put Klinkman into action.
Klinkman placed a small electronic device at the top right corner of the door, next to the frame, and slid the device down to the doorknob. The device displayed a green LED, which turned red about halfway down the door. He pressed a small button on the device with his thumb as it turned red, leaving a small black dot on the white door. He repeated the process under the doorknob, moving the device to the floor without a break in the green LED color.
He reached down into a small bag attached to his waist and pulled out a small thumb-sized charge called a "popper." He placed the malleable charge over the small black dot and pressed it against the frame. If affixed correctly, the
