Shark in kilos Chinese statesman devours (4)
I believe the answer is:
mako
'shark' is the definition.
(I know that mako is a type of mackerel shark)
'kilos chinese statesman devours' is the wordplay.
'kilos' becomes 'k' (this might be a standard abbreviation of which I'm unaware).
'chinese statesman' becomes 'mao' (I've seen this before).
'devours' is an insertion indicator (inserted letters are devoured).
'k' inserted into 'mao' is 'MAKO'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for mako that I've seen before include "Shark" , "NZ tree" .)
