Quivering sound curtailed by singer in novel (6)
I believe the answer is:
trilby
This could be a double definition.
'quivering sound curtailed by singer' is the first definition.
'trilby' can be an answer for 'singer' (I have seen 'Impressionable singer' mean 'trilby' so perhaps 'singer' could also mean 'trilby'). I'm not certain of the 'quivering sound curtailed by' bit.
'novel' is the second definition.
(I've seen this before)
'in' acts as a link.
Can you help me to learn more?
(Other definitions for trilby that I've seen before include "one by du Maurier?" , "Felt hat with a creased crown" , "one mesmerised" , "Book by George du Maurier - hat" , "Miss O'Ferrall" .)
