oh and in case you were wondering the pink post-it-note has the following upon it:

NATIONAL GRID
0800 111 999
- gas smell
- carbon monoxide

....but in an alternate universe...what was MI6 JOHN signalling....? something around the position of that 'post-it-note' in relation to belle court flats?....and that 'pink note' flat would be...let me see....second floor....number 5?
