Such drama in a stormbound abattoir! (5,3,7)
I believe the answer is:
blood and thunder
'stormbound abattoir' is the definition.
The definition suggests a singular noun which matches the answer.
'such drama in a' is the wordplay.
I cannot really understand how this works, but
'a' could be 'an' and 'an' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for blood and thunder that I've seen before include "Sensational" , "melodrama" , "melodramatic" .)
