About the ending - may contain spoilers
Why did Billy Downes ask his wife to scream?
Why didn't he run while she screamed, but simply wait for Harry to shoot him?
Why on earth did the soldier shoot Harry? They revealed their secret observation post while two(?) platoons were on their way.
And one final question: Why did Harry try to kill Downes? He could have been arrested and convicted for murder. THAT would've been the right thing.
