221B Baker Street – Late Afternoon
The knock was soft.
Polite.
John checked the peephole out of habit, then froze.
There she was—tea in one hand, expression unreadable. No coat today. No combat boots. Just jeans, a soft grey jumper, and the same calculating silence behind her eyes.
He opened the door slowly.
“Hazel,” he said, stiffly. “Or… whatever your name is.”
“Enola,” she said simply. “But Hazel works too.”
She held up the box in her hand. Expensive tea. The kind you can’t get at Tesco.
“I brought peace offerings.”
He stepped aside, trying not to let the tension in his shoulders show.
She saw it anyway.
As she passed, she added lightly, “You’re still scared. But pretending not to be. Points for effort.”
He closed the door behind her. “Tea’s a little on the nose, don’t you think?”
“No,” she said, heading for the kitchen like she’d lived there before. “It’s tradition.”
Mrs. Hudson poked her head out from the stairwell.
“Oh—John, you didn’t tell me we were expecting company.”
John turned. “This is… a friend of Sherlock’s. Just visiting.”
Enola offered her hand sweetly.
“Lovely flat. And the tea smells amazing from down there. You must be Mrs. Hudson.”
Mrs. Hudson beamed. “Well, you’re very polite, aren’t you?”
Enola smiled with perfect softness. “Only when I’m not being interrogated.”
Mrs. Hudson gave a little laugh. “Well, good for you, dear. If you want biscuits, they’re in the blue tin. I’ll be downstairs.”
She shuffled off.
John turned as soon as the door clicked.
“Alright. What’s Mrs. Hudson’s percentage?”
Enola, already unboxing the tea, replied without looking up.
“0.17%.”
He blinked.
“That’s… reassuring?”
“She has arthritis and a soft spot for damaged men. She’s not killing anyone.”
John took a slow breath and sat at the table. “You know that makes you sound insane, right?”
“I’m not insane,” she said, turning the kettle on. “Just efficient.”
She brewed the tea in silence, moving like it was a ritual. She stirred his cup with honey, added lemon—and from her jacket pocket, dropped in a flu tablet.
John raised an eyebrow. “What’s that?”
“Your symptoms were worse today. This one won’t make you drowsy.”
“Thanks,” he muttered. “I think.”
She handed it over and sat down across from him, still as a knife.
“I know you have questions.”
He didn’t deny it. “I’ll start with the obvious. Real name?”
“Enola Holmes. No middle name.”
He nodded once. “Sherlock’s sister.”
She tilted her head. “Only biologically.”
John didn’t push that. “And what’s your relationship with him like now?”
“Statistically complicated.”
“That’s not an answer.”
She smiled faintly. “Then ask a better question.”
John folded his arms. “Are you psychopathic?”
“Yes.”
Simple. Flat.
“And?”
“I’ve studied emotions my entire life. I’ve learned to mimic them. I understand their function. I just don’t feel them.”
She sipped her tea.
“It doesn’t make me evil. Just different.”
He stared at her for a long beat. “You said you were medically discharged from active duty. But Sherlock doesn’t believe it was just a shotgun wound.”
Her eyes lowered slightly. The only flicker of discomfort he’d seen.
“No. That was for the paperwork.”
John leaned in. “So what was the real reason?”
She hesitated.
Then: “Brain cancer.”
John didn’t speak.
She looked up. “It’s not terminal. Not yet. But it’s pressing on parts of my brain that affect control, behavior, mood regulation. It’s… complicated.”
“Have Sherlock and Mycroft been told?”
“No,” she said flatly. “And they won’t be. I’m handling it.”
John studied her face.
“You don’t want them to worry?”
“I don’t want them to interfere.”
That sounded more honest than anything she’d said yet.
John sat back. “You were trained to kill. Conditioned. But what’s your opinion of me?”
She looked at him.
“You’re protective. Emotional. Loyal to a fault. You see the best in people, even when you shouldn’t. You stay with Sherlock because you want to believe he can change—and because you don’t believe anyone else could stand him. You’re wrong on both counts.”
John snorted. “You really know how to charm someone.”
“I wasn’t trying to.”
He took another sip of tea. “And all of this politeness—Hazel, the shy smile, the compliments—it’s fake, isn’t it?”
She nodded. “Mostly. The real me would terrify you.”
He didn’t respond.
She added: “I’m not sorry. But I didn’t come here to scare you.”
“So why should I trust you?”
“You shouldn’t.”
That stopped him cold.
Enola leaned back in her chair.
“We don’t know each other. Not really. I’ve read you. Observed you. But trust? That’s not earned in a week and a conversation over tea. That’s earned over time. And you’re right not to give it freely.”
She watched him carefully.
“But I can assure you of one thing. You will not die by my hand unless every other option is gone.”
John stared at her, throat dry.
“Great. So I’m safe… conditionally.”
She raised her cup slightly, like a toast.
“Welcome to the Holmes family.”
John hadn’t moved.
Neither had she.
The seconds stretched, only broken by the faint ticking of the kitchen clock and the slow swirl of steam rising from their mugs.
He cleared his throat.
“Do you think Sherlock is weak?”
“No,” she said instantly. “But he’s volatile. Obsessive. Self-sabotaging. You keep him balanced. That’s why I haven’t killed you.”
John flinched—just barely—but she caught it.
She took another sip of tea and set the cup down with deliberate care.
He leaned in slightly, voice lower now.
“And do you think I’m a threat to him?”
Enola didn’t answer right away.
Her gaze wandered to the bookshelf, the familiar clutter on the mantel, the faint scuff on the rug Sherlock always pretended not to see.
Then her eyes met his again.
“Not yet.”
John stared at her, jaw tight. “Right. That percentage talk again.”
“Thirty-seven percent,” she said coolly. “That’s the likelihood of you becoming a danger. It’s not static. It fluctuates.”
“Because I care about him?”
“Because you affect him. Emotionally. Behaviorally. He reacts to you. That makes you a variable. And variables can become vulnerabilities.”
John let out a short breath, shaking his head. “You really see people like equations, don’t you?”
Enola looked at him, calm and unfazed.
“I don’t need to like the system for it to work.”
He shifted in his seat. “And if I told you I’d never hurt him?”
She tilted her head.
“I’d say you believe that. But I’ve seen men like you before, John. Loyal, noble, kind to a fault. You’re dangerous in your own way.”
“Excuse me?”
She folded her hands.
“You’d die for him, wouldn’t you?”
John didn’t answer.
Enola smiled faintly. “Exactly. And people who are willing to die for others often become the reason they suffer most.”
The room was too quiet now.
Her voice dropped, colder than before.
“You think I’m brutal because I kill. But love without logic is just as dangerous. Ask yourself, John—how many people have gotten hurt simply because they were trying to protect him?”
John leaned forward, voice hard. “We all have scars. We all make choices.”
She nodded. “Yes. And I’m here to make sure yours doesn’t become fatal. To him.”
A pause.
Then Enola added, quieter:
“I don’t hate you. I admire what you are to him. But that doesn’t make me blind.”
John’s voice was sharp now.
“So this is it, then? You play nice, tell me how close I am to death, and leave?”
“No.”
She stood slowly, gathering the tea cups.
“I came here to tell you that you matter. Not to me—but to him. And that’s enough.”
He stared at her. “And if that changes?”
“Then so does the outcome.”
John rose too, now face to face with her.
“You don’t scare me as much as you think you do.”
She looked him over.
“I know. That’s why I like you.”
He blinked.
She set the cups down gently in the sink.
Turned back.
“And for the record,” she said, quietly now, “I think you’re good for him. I hope it stays that way.”
A pause.
Then she added, whispering it almost like a confession:
“But if it doesn’t… I won’t hesitate.”
John didn’t follow her when she left.
Didn’t ask her to stay.
He just stood in the silence she left behind… wondering if maybe, just maybe, this was what being in Sherlock Holmes’ life meant now:
Calculations. Tea. And an assassin in his chair.
Location: Diogenes Club – Private Wing
It was late.
The lamps cast long shadows on the patterned carpet, and the fireplace crackled softly behind a grate. No voices. No murmurs. Just the steady silence of too many secrets and not enough people brave enough to say them aloud.
Sherlock didn’t knock.
He pushed the door open with more force than necessary, letting it thud behind him.
Mycroft didn’t look up.
He was seated in his usual chair, pale fingers curled around a brandy glass, legs crossed, gaze fixed on the dancing fire.
“You’re late,” he said evenly.
Sherlock ignored him. He stood still, coat wet at the edges, curls damp with rain, and eyes darker than usual.
“She visited him,” he said without preamble.
Mycroft exhaled faintly through his nose. “I know.”
Sherlock stared at him. “You knew she was going to?”
“No. But I assumed she might.”
“And you didn’t stop her?”
Mycroft turned finally, eyes sharp.
“Would you have?”
A pause.
Sherlock’s jaw clenched.
Mycroft nodded slightly. “Exactly.”
Sherlock dropped into the opposite chair without ceremony. His coat remained on, dripping onto the rug.
“She brought him tea. Medicinal. Knew about the flu. Said nothing… but everything.”
Mycroft waited.
Sherlock’s voice was quieter now.
“She told him the truth.”
“About?”
“Her name. Her past. Why she left.”
That made Mycroft blink.
He looked over, expression unreadable. “She told him?”
Sherlock nodded.
Mycroft was quiet for a beat. Then, he swirled the brandy glass slowly, as if calculating something he couldn’t write down.
“She doesn’t just share things like that.”
“No.”
“She didn’t tell us.”
“No.”
“Then he’s the first.”
Sherlock’s eyes narrowed slightly, tone darker. “He’s not the first. He’s just the first who didn’t run.”
They sat in silence again.
The fire cracked once.
Sherlock’s fingers twitched against the fabric of the chair.
“She still sees the world in percentages. I asked her to make his zero.”
“And?”
“She can’t.”
Mycroft didn’t look surprised. “She won’t lie to you.”
Sherlock stared into the fire. “You bugged every room I lived in for years. Tracked me like a threat.”
Mycroft tilted his head. “And you’re still angry about that?”
“I got over it.”
Mycroft gave a faint smile. “Exactly.”
“She did nothing, Mycroft. Just walked in, assessed, drank tea, and left us shaken to the bone.”
“Because she didn’t need to do more. She is the threat. Even when she chooses not to act.”
Sherlock’s voice dropped.
“She would’ve killed him. If the numbers shifted.”
Mycroft nodded once.
“She was always the most decisive of us.”
Sherlock leaned forward now, fingers steepled, brows drawn tight.
“I don’t know if I can stop her. Not anymore.”
“You can’t.”
Mycroft’s voice was flat.
“But she doesn’t want to be stopped.”
Sherlock blinked.
Mycroft continued.
“She’s not here to be understood. She’s here to do what she believes is necessary. And right now, that means watching both of us more closely than ever.”
Sherlock processed that in silence.
Then:
“She’s not telling us everything.”
Mycroft nodded. “Clearly.”
“You think she’s hiding the reason she was pulled from the war?”
“I know she is. The official discharge says medical issue. But she won’t give details, not even under royal authority. That’s not procedure. That’s intent.”
Sherlock’s voice lowered. “So you think it’s serious.”
“I think it’s private. Which, with her, is worse.”
A pause.
“She’s not scared.”
“She never was.”
Another pause.
Then Mycroft finished his drink in one smooth motion.
“When she was seven, Mother told me she’d never love us properly. That we’d have to accept it. But I don’t think she was right.”
Sherlock didn’t speak.
Mycroft’s voice softened—barely.
“She doesn’t love like we do. But she’s loyal. And to her, loyalty is just love with discipline.”
The silence stretched.
And then, softly, Sherlock whispered—
“She kept the percentage low.”
Mycroft nodded.
“She didn’t have to.”
