Crossword Genius

Sweetheart from Vienna let off (9)

Ross

I believe the answer is:

valentine

'sweetheart' is the definition.
(I know that valentine is a type of sweetheart)

'vienna let off' is the wordplay.
'off' is an anagram indicator.
'vienna'+'let'='viennalet'
'viennalet' anagrammed gives 'VALENTINE'.

'from' is the link.

(Other definitions for valentine that I've seen before include "Anonymous love token from an admirer" , "Saint regarded as the patron of lovers" , "Potential lover" , "One of Shak.'s Two Gentlemen" , "Card to sweetheart" .)

I've seen this clue in The Telegraph.
