River in the Rhine valley (4)

I believe the answer is:

neva

'river' is the definition.
(I know that Neva is a river)

'in the rhine valley' is the wordplay.
'in' indicates a hidden word.
'NEVA' can be found hidden inside 'rhine valley'.

(Other definitions for neva that I've seen before include "Woman" , "runner in St Petersburg" , "St Petersburg river" , "distant river" , "banker in Russia" .)

I've seen this clue in the Evening Standard.
