Forgotten Lover (parentlock/johnlock)

Part 14

Hamish POV 1
Sherlock pulled out his phone.
S- Gavin, get here as fast as you can, we have our man
Zachary looked at him in disbelief.
Z- you have you man then Mr Holmes, another case solved. Well, I better be off, will buy the paper tomorrow to find out all the details
He turned to the door and two of Lestrades pals stopped him in his tracks. He turned to look at us.
Z- what's all this about?
S- you are our man Zachary. Knew you were the man as soon as you stepped foot in the ward
H- I'm really confused
He gave me a look that silenced me.
S- sadistic
Zacharys face dropped.
Z- they really are as good as they say aren't you, I'd really like to see you suffer
Lestrades pals stepped forward but Sherlock lifted a hand and they stopped, stepping a few spaces back.
S- you're dad, he lost his card, you said he'd given it to you, yet he thought he'd lost it. Walking down the corridor he said you didn't have access so he'll take us, however you seemed to have a very simple access card that you're not meant to have. Your dad isn't an exactly intelligent man, it was easy for you to get away with anything because he trusted you too much. The sadistic part of you is easy to see, going by the cuts up your arms and every visible space on your body. I also noticed you pressing on patients scars when they'd just had their operations, you didn't catch me watching, but you smiled when they were wriggling in pain, you were saying it was doctors procedures
Zach did nothing but stood for a moment then nodded.
Z- you're right, the man, he was a nobody, no family, no wife, no kids. He wanted his life to be over and I just did the thing for him, like a business, but I get something good out of it. I didn't even do it for the money, I did it for him and mail myself
He flashed a blood-curdling grin, making me scared, this kid was a psycho. The police were looking at Sherlock as if to say "what do we do?", however Sherlock was observing Zachary calmly, considering he had just admitted to a murder and all. Dad was looking at me and back to Zachary. It was to silent and I didn't like it. However, I wish it remained silent, because the next thing I knew I was being tackled to the ground and shouts filled the room. I was oblivious to what was being said, because a sharp pain filled my arm and my eyes began to close, shutting everything out around me.
