Sherlock hung the long rope outside his window and tied the end to a near b chair leg before wedging that underneath the door handle.
'C'mon Sherlock!' John yelled 'come out! I'm sorry!'
Sherlock wedged himself onto the windowpane with his suitcase and violin case in one hand and the other gripped onto the rope.
'Now, dear' he heard the voice of Mrs Hudson plead 'this is very stupid. Why don't you open up the door and I'll make us all a nice cup of tea.'
Sherlock shook his head in fury 'I don't want tea!' he yelled 'I want my cigarettes! I don't want those stupid patches or a plateful of biscuits or a cup of tea. I just want my cigarettes.'
'I am sorry!' John yelled 'I just thought… well you did say you wanted to go cold turkey!'
'But I didn't want you to burn my emergency supply, John!' Sherlock yelled 'now, I am going to the shop to buy a packet of cigarettes and then maybe buy a newspaper. After that I am going to stay with Mycroft until I can forgive you.'
'But you hate Mycroft' John said.
'I hate you more at the moment!' Sherlock yelled.
'So does that mean you are going to come out then?' John asked in a hopeful voice.
'I am going to leave this room, but not via the way you think' Sherlock replied with a smile 'you know my methods, John. Not door, but window!' and with that Sherlock swung through the window and down the wall until he reached the bottom 'Goodbye John, Mrs Hudson.'
Sherlock took to running down Bakerstreet with John close in tow
'Sherlock, come back! You're being stupid!'
Sherlock swung out his arm for a taxi and as he jumped in he yelled 'maybe you'll think twice before burning my emergency supply of cigarettes!'
