Novel organisation taking a small part in the summer show (6)
I believe the answer is:
smersh
'novel organisation' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'a small part in the summer show' is the wordplay.
'a small' becomes 's' (abbreviation - e.g. clothes size).
'part' indicates putting letters inside (the inserted letters split open or part the word).
'in the' means one lot of letters goes inside another.
'summer' becomes 'smh' (I can't justify this - if you can you should believe this answer much more).
'show' becomes 'ER' (US medical drama).
'smh' enclosing 'er' is 'smerh'.
's' put inside 'smerh' is 'SMERSH'.
'taking' acts as a link.
Can you help me to learn more?
