"The BFG" author
I believe the answer is:
dahl
'the bfg author' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dahl that I've seen before include "'Roald ..., children's author (4)'" , "Split pulses used in Indian cooking" , "Roald -, British writer" , "Roald or Sophie?" , "British author, notably of children's books, d.1990" .)
