He is officer getting drunk -- what's the drink? (5,6)
I believe the answer is:
irish coffee
'the drink?' is the definition.
(Irish coffee is an example)
'he is officer getting drunk' is the wordplay.
'getting drunk' indicates anagramming the letters.
'he'+'is'+'officer'='heisofficer'
'heisofficer' with letters rearranged gives 'IRISH COFFEE'.
'what's' is the link.
(Other definitions for irish coffee that I've seen before include "Hot, post-prandial whiskey drink" , "Whiskey-enhanced caffeine-based beverage" , "Drink with added whiskey" .)
