Codes
Sort of sequel to codes and communication. No worries if you have not read that, you'll only miss some references. Finished for now, but I will add when inspiration strikes. And suggestions are welcome.
Chapter 1: like in Harry potter
Lestrade called John, he needed their help and I-prefer-to-text Sherlock was not picking up his phone. 'Sherlock, we have a case.' 'How do you know, why did Lestrade call you?' Sherlock demanded. 'If you had answered your phone you would have known.' John answered calmly, used to Sherlock's overreactions to things he thinks he should know first.
John went to put his jacket on and by the time he was done Sherlock had somehow also put his coat and scarf on. 'Come John, the game is on' he jelled, already thundering down the stairs. John sighed, and followed him out the door.
Lestrade looked up from his report when the door of his office swung into the wall, he saw Sherlock walk in with John one step behind him.
'Good, you're here. This is the note in question, and if you damage my wall or door you are paying for it Sherlock. Hello John.' Sherlock ignored his comment about damage and accepted the note without comment. At least John was kind enough to inquire about what was already uncovered about the case (two children had been kidnapped by their father and an accomplice and one of them had left a coded note) and smart enough because Sherlock sometimes forgot that when a crime scene was cleaned up he could not look at it anymore.
John walked over to Sherlock when he was done jotting down the useful info he got from Greg.
The note said:
Emoh kcab su gnirb esaelp. Ymmom gnillet tuohtiw looprevil ot evael ot dah ew dias osla yeht. Anna eitnua ot gnihtemos od ot gniog era egroeg elcnu dna dad.
Sherlock was still looking at it slightly puzzled, this were not shuffled letters and it was also not written with a mirror, nor with that stupid number trick John had used some time ago. He looked up surprised when John read aloud 'Dad and Uncle George are going to do something to Auntie Anna. They also said we had to leave to Liverpool without telling mommy. Please bring us back home.'
'How?' was the only reaction he got, tough Sherlock and Greg said it at the same time. 'It is written backwards' he explained 'Harry liked writing like that when we were younger.
'Donovan, does the suspect's brother have an address in Liverpool?' Lestrade yelled through the still open door. 'Yes he does.'
And the office went empty a few seconds after she gave the address, it was a funny sight to see thought DI Dimmock, all those people rushing out the building.
