Doctor thrown into Russian river under cover of darkness (6)
I believe the answer is:
umbral
'under cover of darkness' is the definition.
I can't judge whether this definition defines the answer.
'doctor thrown into russian river' is the wordplay.
'doctor' becomes 'MB' (Bachelor of Medicine, Medicinae Baccalaureus).
'thrown into' means one lot of letters goes inside another.
'russian river' becomes 'ural' (I've seen this before).
'mb' placed into 'ural' is 'UMBRAL'.
Can you help me to learn more?
(Another definition for umbral that I've seen is " Of shade or shadow".)
