THE QUIET NURSE WAS THE CONSTANT JOKE OF THE RURAL ER—UNTIL HER CALLSIGN CAME OVER THE RADIO AT 3 A.M.

Three people emerged from the vehicle: two military medics and a broad-shouldered officer whose uniform was dark with water. He moved with a pronounced limp, favoring his right leg.

Annie recognized him before he crossed the threshold.

Captain Elias Mercer.

Seven months ago, Mercer had been the commanding officer of the team that extracted wounded personnel from a collapsed field position overseas. He had been the man who ordered the final evacuation when the structure began to burn.

He had also been the last person to speak to Daniel before the radio went silent.

"Where is she?" Mercer demanded.

Annie stood in the corridor outside Trauma Bay 1.

"Captain."

He stopped.

For a moment, the rain, the hospital noise, and the hurried footsteps seemed to disappear between them.

Then Mercer's eyes moved over her face.

"You cut your hair."

"Yes, sir."

"You changed your name on the roster."

"My name is still Keller."

"That's not what I meant."

His gaze dropped to the sleeve covering her left forearm.

"You should have told us where you were."

Annie's expression hardened. "I requested reassignment. The request was approved."

"After you disappeared from the debriefing and stopped answering every message we sent."

"I answered the official ones."

"Three months later."

She glanced toward the trauma bay.

"Captain, we have patients."

Mercer stared at her, then gave one short nod. Whatever argument he had brought with him, he understood that she would not have it in a corridor while wounded men waited for treatment.

"One of the men is in bad shape," he said. "The other two are stable. The unresponsive casualty is in the vehicle behind us."

"Who?"

Mercer hesitated.

That hesitation frightened her more than the answer would have.

"Daniel's younger brother."

Annie's face lost its color.

"Daniel didn't have a brother."

"He did. Half brother. They weren't close. He found us three weeks ago and insisted on joining the recovery team."

"Recovery team for what?"

Mercer looked at her as if she had asked him to explain why the sky was blue.

"For the evidence."

The words landed between them.

Seven months earlier, Daniel Morrow had been listed as killed in action during a classified operation. The official report described an explosion, structural collapse, and an unsuccessful recovery attempt.

Annie had been the senior combat medic at the scene.

She remembered smoke swallowing the corridor. She remembered Daniel shoving a wounded soldier into her arms and ordering her to move. She remembered the blast that knocked her against a wall and left metal fragments in her arm.

She remembered searching for him until someone physically dragged her away.

What she did not remember was seeing his body.

Because she had never seen it.

"Why didn't anyone tell me about his brother?" she asked.

"We didn't know about him until recently."

"That doesn't explain why he's here."

Mercer lowered his voice.

"Someone has been moving pieces of the operation. Reports changed. Names disappeared. A witness was transferred without authorization. Last week, Daniel's brother received a message from an account that should have been deactivated seven months ago."

Annie stared at him.

"What did it say?"

"Three words."

He reached into his pocket and produced a folded piece of paper, protected inside a clear plastic sleeve.

Annie opened it.

The handwriting was familiar enough to make her fingers go numb.

ANGEL SIX IS ALIVE.

She looked up sharply.

"Where did this come from?"

"An encrypted channel linked to the old mission."

"That channel was shut down."

"Exactly."

A shout rose from the emergency bay.

"Captain! We need you!"

Mercer turned toward the doors.

Annie caught his arm.

"Tell me something first."

He looked down at her hand.

"Did you see Daniel die?"

Mercer did not answer quickly enough.

Her grip tightened.

"Captain."

"I saw the position collapse," he said. "I saw the fire. I saw the extraction team pull three men out."

"That wasn't my question."

His eyes met hers.

"No. I didn't see his body."

Annie released him.

For seven months, she had tried to force herself to accept a death she had never witnessed. She had accepted the folded flag, the closed coffin, the official report, and the pity in the eyes of people who believed they understood what she had lost.

Now the foundation beneath that grief was shifting.

Mercer headed for the trauma bay.

Annie remained in the corridor, staring at the message.

Then she noticed something on the back of the paper.

A second line had been written in tiny letters.

ASK WHO SIGNED THE REPORT.
