Night flier turns up for a check (3)
I believe the answer is:
tab
'a check' is the definition.
(I know that check can be written as tab)
'night flier turns up' is the wordplay.
'night flier' becomes 'bat' (I've seen this before).
'turns up' says the letters should be written backwards.
'bat' written backwards gives 'TAB'.
'for' is the link.
(Other definitions for tab that I've seen before include "Till bill" , "Flap; meal bill" , "Tally of orders in bar" , "Marker" , "Small flap - bill" .)
