Wealthy holding company evading tax, at first glance (8)
I believe the answer is:
ricochet
'glance' is the definition.
(I've seen this in another clue)
'wealthy holding company evading tax at first' is the wordplay.
'wealthy' becomes 'rich' (similar in meaning).
'holding' is an insertion indicator.
'company' becomes 'co' (abbreviation).
'at first' suggests taking the first letters.
The first letters of 'evading tax' is 'et'.
'rich' going around 'co' is 'ricoch'.
'ricoch'+'et'='RICOCHET'
(Other definitions for ricochet that I've seen before include "Film" , "Spring back" , "Glance" , "Rebound from surface as missile might - hectic or what?" , "indirect hit" .)
