Kathy sat on the ground against the tree near Sherlock's grave and stared at it. She had given her brother a grave but never visited.
"You know, staring at it won't make him come back." John said approaching the grave with Mrs. Hudson.
"Nice to see you too." She said not giving eye contact.
There was a few moments of silence. It's been just about 8 months since Sherlock's suicide, every month John and Mrs. Hudson stopped by to visit, every month Kathy would be sitting at the tree staring at the grave but something was different this time…
Kathy moved in with John to help with the rent. She moved into Sherlock's room. John would see every day, they left the flat at the same time to go to work, meet for lunch when they could and arrived home around the same time. He also knew when Kathy would be at the grave to visit but lately she's been leaving the flat early, never meets up for lunch any more, and she's never really home until almost midnight.
Mrs. Hudson gave a pat on John's shoulder and headed back to the cab. Once she was a ways away John took this as an opportunity to talk.
"What have you been up too lately?"
"Stuff." Kathy said.
"What sort of stuff?"
"More work stuff."
"That why you out later?"
"Yes, is that a problem?"
"No, but you've been quite secretive lately."
"And I can't have a life without you in it because?"
"I am not going to your therapist. I don't need her, just because you and I are friends doesn't mean I share everything with you. I have a life now, let me live it." Kathy said making eye contact.
John saw the bandage that was on the left side of her forehead, "What happened?"
"Nothing of your concern."
John left it at that, realizing that she wasn't going to talk now so he decided to wait, "Well, I better go."
"You can come out now." Kathy called out as she watched John get into the cab, "When can I tell him?"
"When our business it finished." The man said coming from behind the tree.
"You know, I was never good at all this lying. If it was you I was lying to, I might have been caught by now."
"I hate it just as much as you do."
"Do you? Because emotionless face says otherwise. Why are you hiding Sherlock? Who was the guy I just killed last night?" Kathy said standing up to face Sherlock.
Sherlock didn't say anything… He couldn't. Not yet.
"Fine, don't tell me but he needs to know you're alive. He's practically dying on the inside and I can tell you his therapist isn't helping. He needs his detective to make his life exciting."
"And what will happen to you?"
"What is this a love story? Sherlock he makes you five times happier than I ever will. Don't you dare look tell me it isn't true. What we had, all those years ago, was real. I was the happiest girl on earth but now I'm miserable, because you are married to your work and I'm dying."
"We can make this work. I'll learn."
"You don't get it. I'm sick Sherlock. I'm going to die. I didn't just come back to help you but I came back to tell you."
"What do you have?"
"Does it matter? You can't save me, even if I let you. Tell John, Sherlock. He needs his friend." Kathy said walking off.
-Back at the flat-
John finished making tea and went to sit at his laptop as Kathy walked into the kitchen.
"I had surgery. That's why I have a bandage on my forehead, but really it's the side of my head. I'm just wearing a wig." She told John.
"Surgery for what?"
"It doesn't matter."
"Yes it does."
"No John it doesn't."
"Then what does?"
"I'm dying." Kathy said walking off to her room.
John just sat there, letting the words echo through his head. He put his hands on his face then went to Kathy's room. The door was open so he just walked in and found Kathy on the bed with a book in hand.
"How long do you have?"
"Doctor says any day now. My will's on the desk over there, when you need it."
"You seem calm for someone who's just about to…. I'm sorry about earlier, I didn't-"
"Don't worry about it."
"Do you need anything, want anything?"
"No, thanks though."
John nodded his head and left the room. Another death… Well at least she'll be with Sherlock.
Later that night Kathy died in her sleep and wasn't found until morning. Her funeral was a week later.
John was cleaning out Kathy's room when he ran across a letter addressed to him on the night stand. He sat on the bed and read it:
I must be dead if you're reading this but Sherlock's alive. He didn't want me to tell you but you have to know. I don't know why he didn't want me to tell you but I couldn't let it die with me. You don't have to believe me. I never asked you too, but believe me when I tell you this… I am alive and well. Who knows, I may show up one day and pronounce that I'm alive.
Sherlock thinks that I have 3-4 months to live. Remember when you went to the grave last and I was there. A month from then is when we met, go then and call out his name and announce that I'm dead, he should appear but I can't promise anything.
"John… You have a visitor." Mrs. Hudson said.
John nodded his head and went to the living area. Once he opened the door, his mouth gave a bit of a drop.
"April Fools John. Not dead." Sherlock said hopping to get a chuckle.
John just shook his head.
"Where's Kathy? I'm sure she'll get a kick out of this."
"Dead. She died in her sleep about a week ago, and you with her."
Sherlock just stared at John.
"You know, I thought she was joking when she said you were alive. Thinking she would die that night, knowing that I would find the note she left me today. She says that she's alive in the note too but I don't believe it for a second."
"She is alive John. She has a family of her own that she couldn't bare to tell me about."
"Don't back up her story! She's dead! I checked her pulse just like I checked yours!"
"Moriarty was going to kill you John, along with Mrs. Hudson, and Kathy is alive. She has a husband, a little boy and girl too."
"You weren't supposed to know."
"She doesn't know that I do. The man she married, doesn't know the real her. John I'm sorry for hurting you it was the only way I could save you."
"And Mrs. Hudson."
"Well then, if you want your room back. You can pack up the rest of her stuff, I'm going to bed." John said leaving the room.
Sherlock stood where he was and he got a text.
Thank you for saving me SH. Maybe you could meet the family when the children are older.
Well, this is the end. I hoped you enjoyed it.
