German river (German spelling) (5)

I believe the answer is:

rhein

(Other definitions for rhein that I've seen before include "Locally busy European river" , "You might find her in the river, strangely" , "(German name for) German river" , "In Germany, find her in the river, strangely" .)

I've seen this clue in The Guardian.
