Journey's End by RC Sherriff, a play
It's for my eng lit course, and it's splendid and spiffing. it's centred on the officers of world war 1, so the language is sort of (from what i've read so far) in that upperclass way of conversing;
"Hullo Osborne! Your fellows arriving?"
"Yes. They're just coming in"
"Splendid! Have a drink"
