Run fails to open after boycott of comic role (10)
I believe the answer is:
blackadder
'comic role' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'run fails to open after boycott' is the wordplay.
'run' becomes 'ladder' (both can mean a rip in tights).
'fails to open' means to remove the first letter.
'after' says to put letters next to each other.
'boycott' becomes 'black' (black list).
'ladder' with its first letter taken away is 'adder'.
'adder' after 'black' is 'BLACKADDER'.
'of' is the link.
Can you help me to learn more?
(Other definitions for blackadder that I've seen before include "TV show" , "Recurrent historical character on TV" , "Comedy hero" , "Cash desk" .)
