Alcoholic beverage is found in her office, sadly (5,6)
I believe the answer is:
irish coffee
'alcoholic beverage' is the definition.
'Irish coffee' can be an answer for 'beverage' (Irish coffee is an example). I am unsure of the 'alcoholic' bit.
'is found in her office sadly' is the wordplay.
'found in' is an insertion indicator.
'sadly' indicates anagramming the letters.
'her'+'office'='heroffice'
'heroffice' anagrammed gives 'irhcoffee'.
'is' going into 'irhcoffee' is 'IRISH COFFEE'.
Can you help me to learn more?
(Other definitions for irish coffee that I've seen before include "Whiskey-enhanced caffeine-based beverage" , "Hot, post-prandial whiskey drink" , "Drink with added whiskey" .)
