MF-Man

Based on the release rate, the critical point for a lethal dose was still about five to seven years away.

In other words, if no one found the micro-capsule, Black Widow would suddenly suffer a nervous system collapse and die for no apparent reason in five to seven years.

And she had no idea.

Lynn moved his hand away from the back of her neck and came around to sit in front of her.

He looked into "Natalie Rushman's" eyes.

"Ms. Rushman, your body is in far more danger than you think."

"What do you mean?" Her tone was still light, like that of an ordinary person coming in for a checkup.

"There's something very small beside your seventh cervical vertebra," Lynn said, enunciating every word clearly. "It's about the size of a sesame seed. It was implanted when you were very young."

Her pupils contracted.

It lasted only an instant, but Lynn saw it clearly.

"If it isn't removed," he continued, "you probably have about five to seven years left to live."

The examination room fell silent for a full three seconds.

It wasn't an ordinary silence.

It was the silence of a highly trained top agent reassessing the entire situation in an instant.

"What are you talking about?" She gave a little laugh, still trying to sound casual. "I'm just here for an ordinary checkup—"

"It's a slow-release neurotoxin micro-capsule," Lynn finished for her.

"It releases its contents over about fifteen to twenty years. Seventy-two percent has already been released. Once the remaining twenty-eight percent reaches the critical threshold, your entire nervous system will collapse within forty-eight hours. Irreversibly."

She stopped smiling.

The "ordinary woman here for a checkup" disguise had developed its first crack.

It wasn't fear. A woman raised in the Red Room wouldn't be afraid of death. It was shock.

She hadn't known it was there.

"How could you possibly know that?"

Her voice dropped half an octave, and her right hand had already crept toward a spot inside her sleeve.

Lynn's tactile perception picked up a faint electrical pulse—a stun device.

Her fingers were already on the switch.

"Because I'm a doctor." Lynn leaned back in his chair.

His tone was so calm, it didn't sound as if he were announcing someone's death. "It's my job."

"How could you see something 0.3 millimeters across? You didn't even use any equipment."

"I did." Lynn pointed to his head. "This is my best instrument."

She stared at him for five seconds.

Lynn kept smiling the whole time.

He knew what she was doing—using every people-reading skill she'd been trained in to analyze him.

She was studying his microexpressions, his breathing, his pupils, trying to decide whether he was telling the truth or bluffing.

After five seconds, her right hand moved away from her sleeve.

"You know who I am." It wasn't a question.

"Ms. Rushman, all I know is that you have a time bomb beside your seventh cervical vertebra." Lynn stood up. "Who you are isn't my concern. What I care about is—do you want it removed?"

She didn't answer.

She stood, straightened the hem of her sweatshirt, and headed for the door.

She paused just before leaving.

"Aren't you afraid of me?"

"I'm a doctor," Lynn said. "Being afraid of a patient would be unprofessional."

She looked at him.

There was a lot in that look—scrutiny, assessment, and a hint of an emotion he couldn't quite read.

Then she opened the door and left.

The six men in dark suits outside the clinic immediately followed her and disappeared around the corner.

Frank lifted his head slightly from the folding chair. "Who was that?"

"Someone here for a checkup."

Frank grunted and didn't ask anything more.

Lynn went back to the front desk and sat down, picking up his coffee, which had gone cold.

After she went back, she would do two things.

First, contact Fury and report what had happened.

Second, have S.H.I.E.L.D. verify his claims with the most advanced equipment available.

If the results matched what he'd said, Fury's assessment of his value would jump three levels.

At that point, the initiative would be entirely in his hands.

Lynn took a sip of cold coffee and smiled faintly.

The first thing Natasha did when she returned to the Safe House wasn't change clothes or remove her gear. She picked up the encrypted communicator.

"Romanoff to Control."

"Go ahead, Agent Romanoff. Director Fury is on the line."

"Play him today's recording, starting at the seven-minute mark."

There was silence on the other end for about forty seconds.

During those forty seconds, Fury listened to the recording.

Natasha stood beside the Safe House window, unconsciously touching the spot on the back of her neck beside her seventh cervical vertebra.

She couldn't feel anything.

That spot felt no different from anywhere else on her body.

"What's your own impression?" Fury's voice came through the communicator.

"I don't think he was lying."

"An impression isn't enough. I need data. Go back to the District 3 Base and get a full quantum-level imaging scan, top priority."

"Understood."

Natasha ended the call and left the Safe House.

She didn't call a car. She walked two blocks before hailing a taxi.

Sitting in the back seat, she touched the back of her neck again.

The Red Room.

She'd thought she'd severed every tie to that place.

She'd thought that after defecting, all the Red Room had left inside her, aside from memories she couldn't erase, were the instincts it had trained into her and a body covered in scars.

But the Red Room had been more thorough than she'd imagined.

It hadn't killed her. It had installed a timer.

She'd thought she was free, but the date of her death had been written the day she left.

Natasha lowered her hand from her neck and clenched it into a fist.

Three hours later, in the medical laboratory at S.H.I.E.L.D.'s District 3 Base.

The quantum imaging equipment ran for forty-five minutes.

A full-body scan, with precision down to the micron.

When the senior technician operating the equipment pulled up the results, his hand trembled.

"Agent Romanoff, 2.1 millimeters beside your seventh cervical vertebra... there's indeed a cystic foreign object. Its diameter is about 0.3 millimeters. The composition analysis shows... it isn't any known medical implant."

Fury stood behind the technician, his single eye fixed on the tiny bright spot on the screen.

"Magnify it."

The image was magnified to its highest level.

The structure of the capsule became clear on the screen. Its outer shell was made of an ultradense biom metal alloy, and its interior was filled with a viscous liquid. Countless microscopic molecular chains were dispersed throughout the liquid.

The technician's voice trembled. "Director, our database has no matches for the capsule's shell material. But preliminary analysis of the liquid inside shows it contains an extremely complex neurotoxin. Its purity is very high."

"What's the release progress?" Fury asked.
