A popular success in Wichita (3)
I believe the answer is:
hit
'a popular success' is the definition.
(I've seen this in another clue)
'in wichita' is the wordplay.
'in' indicates the answer is hidden within the clue.
'HIT' is hidden in the letters of 'wichita'.
(Other definitions for hit that I've seen before include "Adversely affected" , "Knock" , "dose of illegal drug" , "Murder" , "turkey? No" .)
