Knox discovery

I just found a book for the holiday, an astounding find since four of the six mysteries Knox wrote have been OOPed with prejudice. I have read the two in print, but the other four command ludicrous prices on abebooks.

Of course I will be violating American copyright law when I read that, since it is merely 81 years old. In Johnson's time copyrights lasted less than twenty years, which does seem too short, but the hundred years he proposed, and that thanks to Disney is now the law in the U.S., is surely far too long. Even excellent books fall out of print long before a hundred years elapses.
