Tent fire destroyed one Egyptian queen (9)
I believe the answer is:
nefertiti
'egyptian queen' is the definition.
(I've seen this before)
'tent fire destroyed one' is the wordplay.
'destroyed' indicates an anagram.
'one' becomes 'i' (Roman numeral).
'tent'+'fire'='tentfire'
'tentfire' with letters rearranged gives 'nefertit'.
'nefertit'+'i'='NEFERTITI'
(Other definitions for nefertiti that I've seen before include "Name of queen" , "Beautiful queen who ruled Egypt with the Pharaoh" , "Oddly, the Egyptian queen is an entire fit" , "Egyptian queen, the wife of Akhenaton" , "Egyptian beauty queen" .)
