With the needle in the sealed police report bag and with their permission, John was on his way to the lab to see Molly and get her to check was in the needle, if it was poison, he needed to be careful so he didn't get any on his clothes and then on to Mary or William.

Molly already knew about the poison so was ready when he got there.

one hour later she was ready

' John this is a poison called 12a, very rare and the antidote is even rarer, only two bottles ever made, the government have one and god knows were the other has got too '.

John's face went white

'Whoever has it will have Sherlock, Molly we think that Sherlock has been kidnapped and was poisoned with it' he showed her the note.

' not possible, 12a only takes 24 hours to kill a person, starting out with blackout dizziness, painful cramps and then the body shut's itself down however...'

Molly ran to the bookcase and pulled down a big heavy book with poisons written on it

' John if Sherlock has been poisoned, this might explain the note, listen, in 1924 a man called dr re found that 12a can slow down 40% when in temp at 2.c. he got permission of the US government to test out this on death row inmates. once given the drug they had the same affects but over the course of a week, not 24 hours, this person John is doing this to Sherlock'

when Molly looked up she saw a look of pure anger in Johns face.

' this man is making Sherlock wait for his death in pain because he

finds it funny, seeing who will win, death or us! Well I will find him and will make sure his heart is still beating as well'

Molly was in tears by this point

'but John if you do find him, he will be already dead or he will hold on to make sure you do find him, he wont make it'

' he better, as i am going to start by ringing someone that counts.

'Who?'

'His Brother'

John dialled the number for Mycrofts brother and hailed it to his ear and listened to the tone of his phone ringing.

' come on pick up, this is important'

finely the phone picked up

' hello'

Mycroft it's John, this is important, yes yes, look it's about Sherlock, he's missing and we think he is in danger, right, right, ok, thanks'

when John drop the phone Molly knew it was good, he's on his way and John knew he may have saved Sherlock some time.
