Go like a shot! (5)
I believe the answer is:
essay
I believe this is a double definition.
'go' is the first definition.
(thesaurus)
'a shot' is the second definition.
(thesaurus)
'like' is the link.
(Other definitions for essay that I've seen before include "Attempt, try" , "Make an effort to write one" , "Analytic or interpretive literary composition (5_" , "Composition, paper, article" , "Short formal piece of writing" .)
