Proceed carefully and quietly and, in the bond, turn the page over (6)
I believe the answer is:
tiptoe
'proceed carefully' is the definition.
(I've seen this in another clue)
'in the bond turn the page over' is the wordplay.
'in the' indicates putting letters inside.
'bond' becomes 'tie' (both can mean a connection).
'turn the page over' becomes 'pto' (I am not sure about this - if you are sure you should believe this answer much more).
'tie' enclosing 'pto' is 'TIPTOE'.
'and quietly and' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for tiptoe that I've seen before include "Go carefully" , "Walk delicately - musically through the tulips" , "Move stealthily, with heels raised" , "Be careful" , "Move with stealth" .)
