Ernest Hemingway WWI novel (1,8,2,4)
I believe the answer is:
a farewell to arms
(Other definitions for a farewell to arms that I've seen before include "experience for the Venus de Milo?" , "what one handing in weapon might say" , "valediction from the Venus de Milo?" , "Work of Ernest" , "comment on the Venus de Milo?" .)
