Lost and Found (Sherlock x Reader)

The Final Problem (Part 6)

"But what about the plane?"

"Well, the puzzle will save the plane." He observed a few more inscriptions. "The wrong dates. She used the wrong dates on the gravestones as the key to the cipher..." He found the gravestone of Nemo Holmes and paused there.

NEMO

n. [nee-moh]

Latin - no one, nobody

"...and the cipher was the song."

You and John both were able to hear Sherlock's ramblings as Eurus reconnected you all.

"Is this strictly relevant?" John shouted over the rushing water.

Both of you were trying to stay above the water, but that was proving to be more and more difficult. You kept your gaze down towards the bottom of the well—down where your brother had been left—where the chain still pulled at your leg, threatening to drown you.

"Yes it is," Sherlock answered John. "I'll be with you in a minute."

The detective compiled all of the information he had just collected. The names on the stones as well as the false dates. Using his mind palace, he pictured the words of the song and the numbers from the gravestones floating in the air in front of him.

"The lights are getting closer," The girl cried.

"Hush, now. Working." He held his hands out to the side as he stared at all the words and numbers. "Let's number the words of the song." The numbers floated above the song lyrics. "Then rearrange the numbered words to match the sequence on the gravestones."

Words spun around and faded, leaving just the sequence the detective needed. As the words came to him, he ordered them and said them aloud.

"I...am...lost...Help...me...brother...Save...My...Life...Before...my...Doom...I...am...Lost...Without...your...love...Save...My...soul...seek...my...room."

When he said the last word, his expression dropped as he realized the answer. "Oh, god."

He grabbed his lantern and quickly ran back towards the house. He burst through the front door, hurrying up the stairs.

"We're going to crash!" The girl screamed in Sherlock's earpiece. "I'm going to die!"

He then heard you and John grunting as you struggled to survive. Sherlock went faster.

"I think it's time you told me your real name," He said to the girl.

"I'm not allowed to tell my name to strangers."

Sherlock paused outside Eurus's bedroom door. "But I'm not a stranger am I?" He asked, his voice quieter. He turned the handle and stepped into the room. "I'm your brother."

On the floor a few feet away from him, Eurus sat with her eyes closed and her knees pulled close to her chest. The detective carefully approached her, setting the lantern down on the floor.

"I'm here, Eurus," He said softly to her.

"You're playing with me, Sherlock," Eurus said, her voice taking on a child-like tone—the same voice that had been speaking to him just moments prior. "We're playing the game."

"The game, yes. I get it now." Sherlock stepped closer, standing in front of her. "The song was never a set of directions."

Eurus suddenly gasped in fear. "I'm in the plane, and I'm going to crash. And you're going to save me."

Sherlock knelt down. "Look how brilliant you are. Your mind has created the perfect metaphor. You're high above us, all alone in the sky, and you understand everything except how to land." He seated himself more comfortably, shifting closer to his sister. "Now, I'm just an idiot, but I'm on the ground." He gently placed his hand on top of hers. "I can bring you home."
