He draws actors into trouble (10)
I believe the answer is:
cartoonist
'he draws' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'actors into trouble' is the wordplay.
'trouble' is an anagram indicator.
'actors'+'into'='actorsinto'
'actorsinto' with letters rearranged gives 'CARTOONIST'.
Can you help me to learn more?
(Other definitions for cartoonist that I've seen before include "Heath Robinson, say" , "Low" , "drawer" , "Scarfe, say" , "Eg, Peter Brookes" .)
