Holmes had decided where they were going to meet- the roof of St. Bart's hospital. It was helpful that he'd chosen a tall building.

All the gunmen were in place- one, a man I didn't know, had managed to get inside the landlady's house- he was putting up some shelves or something; Mark Tam, one of our gunmen, had infiltrated Scotland Yard, so was in place to shoot the DI; and Seb and I were sat on the stairs in a almost deserted block of flats, opposite Bart's.

Seb was on the phone to Jim.
"You sure this will work?" He asked.
"...ok...Why are you saying goodbye? It'll be fine... Love you too.." Seb put his phone down. "Jim's acting weird." he muttered.

"Probably just nerves." I said, watching the figure of my brother's boyfriend pace the roof opposite.

"Probably." Seb sighed.

Across the road, Jim had sat down on the low wall that ran all the way around the roof.
Holmes appeared. They seemed to be talking, but we couldn't hear what they were saying.

They were both moving around, obviously talking. Jim seemed happy, but Seb and I could tell, just from his movement, that he was worried about something.
Holmes looked over the edge, down the sheer drop to the pavement below. Jim stood behind him, talking.

Suddenly, Holmes was holding Jim over the edge, threatening to drop him off the building. I heard a sharp intake of breath, and looked at Seb. "He'll be fine." I said.

"I hope so." Seb muttered.

Across the way, Holmes had pulled Jim back to safety, and was saying something.

Holmes stood on the wall, facing, but not seeing, us, while Jim walked away from him.
We saw Holmes laugh. He hopped off the wall, and walked towards Jim.
After a bit, they shook hands, and it was then we heard the bang of a pistol being shot. Holmes backed away, shocked, as Jim fell to the ground.

"No.." Seb whispered."No, no, no, no... no!" he sat on the stairs, his head in his hands.

Jim's words, from when we had chatted that morning while Seb was in the shower, came back to me "Look after him for me?" I had nodded, confused, but now it made sense.

I abandoned my post, and sat next to him, an arm over his shoulders. Seb lent against me, tears streaming down his face. I was crying a bit too, actually. "Come on." I said. "Let's finish this."

He shook his head. I carefully stood up, and went back to my sniper.
Holmes was on the wall, now, holding his phone.
I trained my sniper on his best friend, who was standing our side of the ambulance block, watching in fear as Holmes dropped his phone, and then stepped off the building. It was done.
I immediately turned back to the emotional reck that was my brother.
"Come on, Seb. Let's go home."
He nodded sadly and stood up. I picked up both sniper bags, and we left the block of flats by the back entrance.
