De mortuis nil nisi bonum."
-Poul Anderson, Murder In Black Letter, ebook, Chapter 2.
We have quoted so much Latin that I thought that another aphorism would be appropriate. This one is particularly appropriate in a detective novel. A man has been killed. A man who had argued with him says, "Speak no ill of the dead..." I don't agree with that. If I called a man dishonest or corrupt before he died, then I will continue to call him it after his death.
