Author putting King and Ace following King and Ace (5)
I believe the answer is:
kafka
'author' is the definition.
(Kafka is an example)
'king and ace following king and ace' is the wordplay.
'king' becomes 'k' (abbreviation for king in chess).
'and' is a charade indicator (letters next to each other).
'ace following king' becomes 'afk' (this might be a standard abbreviation of which I'm unaware).
'and' is a charade indicator (letters next to each other).
'ace' becomes 'a'.
'k'+'afk'+'a'='KAFKA'
'putting' acts as a link.
(Other definitions for kafka that I've seen before include "Czech author of The Trial, d.1924" , "Franz ---, Trial, Castle author" , "Franz ....., Czech author of 'The Trial'" , "Author of 'The Trial' (1925)" , "Influential German-speaking existential novelist" .)
