"Ok Sherlock, I'm leaving for work. Please try not to burn the flat down while I'm gone. Text me if there's an emergency. No, being bored does not count. If it's a case...use your judgement, but keep in mind I've already missed 5 shifts this month, I do need to be careful. I should be home by 18:00, there's a casserole in the fridge I was going to bake for dinner, if you remember, please turn the oven on at a quarter-'til for me," John called all of this over his shoulder as he walked to the door of the flat, pulling his jacket on at the same time.
He stops for a moment at the door, looking back and smiling fondly at the sight of Sherlock laying on the couch in his "thinking pose." John walks over and drops a kiss to Sherlock's hair before leaving, the tall man too lost in his mind palace to make any response. John wasn't worried- Sherlock's brain seemed to have a answering machine of sorts that recorded things Sherlock missed while thinking, so he would eventually remember John's words.
John walks out of the flat and takes a moment to pop up the collar of his jacket to try and block the lightly drizzling rain. He walks to the curb and hails a cab, giving the address of the clinic. It takes him 20 minutes to realize that the grey view outside the window is not what it should be.
"What's going on?!" John asks sharply, unlocking the cab door, "This isn't where I asked to go!"
"'Fraid you're going somewhere else mate, now cooperate and stay calm, or else I'll have to make things a bit unpleasant for you."
John opens the door to the cab and jumps out, but doesn't even manage to run more than a few meters when another car pulls up, blocking his path, he turns around again, only to realize that he is in a small back alley and there is nowhere else to run. A team of three men get out of the car in front of John.
A clear sense of calm brought on by the adrenaline flooding his system hits John, and he slips a hand into his pocket. John hits the speed-dial on his phone in his pocket, hearing the ring- the call would go through either to Sherlock, Lestrade, or Mycroft. That done, John makes one last effort to run, but is easily caught by a large man with a crooked nose. He puts up a fight when caught, manages to break a few fingers, and give one of his assailants a black eye, but he is rather quickly subdued. A damp rag is pressed over his face- chloroform.
The ground got fuzzy and started to spin a bit, John heard the men speaking, but it sounded like the words were coming down a long tunnel, "Tie him up, then put him back in the cab, quick. Boss wanted him by the hour, and I don't want to know what would happen if we come late."
Then, everything went black.
