Sherlock was playing outside when a black car pulled up the driveway of his parents beach house. Two men in suits came out and Sherlock could see that they were both heavily armed. Mr and Mrs Holmes came out of the house and showed the two men inside.
Sherlock's mother knelt in front of him, took his hands in hers and kissed them, whispering gently "I love you darling, don't ever forget that okay." He nodded and his father rubbed his back and they both went inside.
He knew that there were several possible outcomes of the unexpected visit, but the one that came to be was the least desirable.
Sherlock heard raised voices and two gunshots. The two men walked out, looked over to Sherlock and walked off. Slowly he got up and walked inside to find his mother and father on the floor, they had both been shot and were both dead. He sat in between them and held their hands.
Several hours passed and Sherlock just sat there doing nothing. His brother Mycroft walked in and was horrified at the sight of his parents and his little brother in between them. He rushed forward and picked up Sherlock leaving the house as quickly as possible. He called the police.
...
John and Sherlock entered the house of a young woman, they had come to break the news that her mother had died.
"Are you police, so did you find out who stole my mum's bag?" the young girl said to them both cheerfully.
"Now Anna, I'd like you to sit down, I have to tell you something." Sherlock said gently pulling a chair out for her while John stood in the corner.
He held out a locket and said "Is this your mum's necklace?"
Taking the necklace she said " Yes, but that wasn't in her bag" Anna looked from John to Sherlock with a confused expression on her face.
"Anna, I'm so sorry" Anna began to cry "they found your mum this morning" Sherlock said putting his hand on her shoulder and looking into her eyes.
"They think it was murder" John added only making the girl wail louder.
"Is there anyone I can call, anyone you'd like to be here?" Sherlock asked still keeping eye contact.
"My boyfriend, Joe" she said wiping tears from her face.
" Well, I'll stay with you until he arrives" turning to John he said " would you call him? the number should be in her phone" John took the phone shocked at this sudden show of humanity from Sherlock.
...
"Sherlock?" John asked as he brought in two cups of tea.
"mhm" Sherlock replied taking the cup.
"How old were you when your parents died?" he asked quietly.
Sherlock's head snapped round, "Where did this come from?"
"Today, with that girl, Anna, you really connected, so I asked around, and well..." he trailed off.
"I was 7" He said taking a sip and standing up. He walked over to a cupboard and took out a photo album. "This is me, that's my mum and here's me dad" he said opening the album and pointing to a photo.
John took the album and smiled, looking through the pictures. Handing it back he said "I'm so sorry about what happened to you Sherlock.
"Thank you" he put away the album and sat back down next to John where they continued to talk about their childhoods.
