From The Day of the Jackal
[Caron calls London, Assistant Commisioner Mallinsion at 3:58 in the morning
I don't wish to sound rude, Inspector, but wouldn't it be better if this sort of routine inquiry could be conducted through the proper channels, preferably when we're all awake?
Yes, I'm sorry Mr. Mallinson, but it is very urgent. Commissioner Lebel didn't wish to make a formal request; he was rather hoping that you'd cooperate with us unofficially.
All right, I'll take the Commissioner's call at... 08:30, you say? Fine. Good night.
