Come next (5)
I believe the answer is:
ensue
'come next' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ensue that I've seen before include "Cultivate plants/vegetables" , "Happen as consequence or afterward" , "Come to pass" , "Occur as a result (of)" , "Happen as a result, follow ( 5)" .)
