Gasp, somehow, at holes (4)

I believe the answer is:

gaps

'holes' is the definition.
(I've seen this in another clue)

'gasp somehow' is the wordplay.
'somehow' is an anagram indicator.
'gasp' is an anagram of 'GAPS'.

'at' acts as a link.

(Other definitions for gaps that I've seen before include "Breaks, spaces" , "Breaks or openings as in hedge or fence" .)

I've seen this clue in The Mirror.
