Part 1.
"Sherlock" yelled John from his room.
"Yeah?" said Sherlock. He was relaxing on the sofa. When I say relaxing I mean that he tried to come up with a new experiment to do.
"If you need anything ask Mrs. Hudson" said John, as he ran down the stairs. He wore dadk clothes and Sherlock could see the gun under his coat.
"Where are you going?" asked Sherlock.
"If I am not back within 12 hours call this number and say that I am out of the picture" said the doctor as he gave Sherlock a paper with a phone number.
"What...John..." Sherlock tried to say something but for once he couldn't say anything. Here stood John before him like a soldier going to the battle.
"Don't worry. If everything go good I'll be back in five hours" John tried to calm Sherlock down.
"And if not...?" asked Sherlock uncertainly. John shrugged.
"I'm am gonna be back" with this John stormed out of the flat. Sherlock looked out of the window and he caught as Watson got into a black car.
2 hours later
Sherlock still didn't find anything on John's laptop. He considered calling his brother, but vetoed against it. He will wait for one more hour than consider it again.
3hours later
He finished with John's room and he still couldn't find anything. There was a photo with John and seven other soldiers on it. He recognised five of them from Mycroft's rescue. The other two he didn't recognised and he didn't find any other photo about them.
4 hours later
"I will call Mycroft" said Sherlock aloud. He got his phone and stared at it. On one side he was worried about John, but on the other side John brought a gun with him and he didn't want Mycroft to find out about it.
5 hours later
It was five hours since John left. Without thinking he called his brother.
"I am on my way" said Mycroft before Sherlock could utter even one word.
Five minutes later Mycroft arrived.
"I was told that the doctor left five hours ago and carried a gun with him" said the elder Holmes.
"He said that he is gonna be back in five hours if everything is good, but if he is not back within 12 hours I am to call this number" he gave Mycroft the paper "and say that he is out of the picture".
Mycroft stared at the phone number. He recognised it. It was one of the most hidden number in England. It was the number of the MI6's head.
"Did he say anything else?"
"No" answered Sherlock. Anathea stood behind Mycroft an did some miracle with his ever present phone.
"Boss, there is an operation in London. The MI6 didn't say who are the agent, but their mission is to find a terrorist group near the port."
"Why would John go there?" asked Sherlock. He knew that his blogger was a soldier, but why would he work for the MI6.
"Sherlock, where did you found this photo?" asked Mycroft. Sherlock forgot that he brought Watson's photo with him downstairs.
"In John's room. Why?" he asked Mycroft. He saw as Anathea also took a glance at the photo and just stare at it in disbelief.
"Do you know who this man is?" asked Mycroft and he pointed at a man, one whom Sherlock wan unfamiliar with.
"No, but the others were the ones who helped to get you out of that warehouse". Mycroft shuddered at this, he didn't want to remember that time, when he couldn't do anything to save himself and others had to do it. After that he tried to find the soldiers to thank them and to ask if they want to work for him, but they disappeared. But this man on the photo...
"He was a general in the East. He good, too good in fact" said Mycroft "he caught every terrorist, but he was cruel. He killed to many people, he lost too many good man during the missions."
"Where is he now?" asked Sherlock.
"Dead" said the elder Holmes "he killed himself" said Anathea.
