The Doctor had always warned Nina never to go into his basement laboratory, and to drive the point home he always kept the sturdy door to the workroom locked. He was so fastidious about this that Nina had never even managed a peek around the corner as he entered the room on days he researched from home or left the room at the end of the day to head to the liquor cabinet for, as he termed it, "some well-earned relaxation." Naturally his secrecy didn't dissuade Nina but, if anything, stoked her curiosity intolerably. So too did the strange odors that sometimes emerged from the laboratory despite the thickness of the basement door, and the implacable sounds that she either heard or imagined: rustling that sounded neither human nor animal; halting footsteps that seemed less like walking than its arrhythmic attempt; grumbles and murmurs that sounded as though they came from a man's throat but had no solid anchor in language.
Nina was apprehensive to learn what her stepdad was doing these many hours and days, what he could be creating that would make sounds of that kind. But the more she asked—and, particularly, when she specifically mentioned the sounds and smells she'd discerned—the more secretive he got, telling her gruffly to concentrate on her own studies and not concern herself with matters above her intellectual station.
Nina's father, the esteemed Dr. Brownmiller, had set the bar high for her. In the thirty years since he'd gotten his Ph.D. from MIT, the Doctor had worked at the Naval Warfare Systems Lab and NIH, performing groundbreaking research on disease and mutation. After that he'd spent 15 years at AgronCo—the biggest bioengineering firm then working in genetically modified crops—and after that, BioFense Ventures. BioFense had been a startup bioweapons counterterrorism research company that soon became DARPA's main private-sector partner in bleeding-edge bioweapons R&D.
