One may get pulled in deception (4)
I believe the answer is:
hoax
'deception' is the definition.
(hoax is a kind of deception)
'one may get pulled' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'a' and 'a' is present in the answer.
The remaining letters 'hox' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for hoax that I've seen before include "Playful fraud" , "A fraud or deception" , "Spoof" , "Deliberate trickery" , "Imposture" .)
