Austrian count’s last letter, dark, yet animated (8)

I believe the answer is:

radetzky

'austrian count's' is the definition.
(18th and 19th-century figure Count Radetzky)

'last letter dark yet animated' is the wordplay.
'last letter' becomes 'z' (last letter of the alphabet).
'animated' indicates an anagram.
'z'+'dark'+'yet'='zdarkyet'
'zdarkyet' is an anagram of 'RADETZKY'.

I've seen this clue in The Times.
