"Now will you tell us how the letters are collected for the post in the morning at the Lodge?"
"They are put into the post-bag, which is locked. His Grace keeps one key and the post-office has the other. The lettters are put in through a slit in the top."
- Dorothy Sayers, Clouds of Witness
(And suddenly I thought: aw, damn, letters.) (I miss letters more than I could ever say.)
