Last PuritanTo George Sturgis
Hotel Bristol
Rome. March 29, 1936

I see the lien that the government has upon the royalties of a person in my position. I am—or my publishers are—protected by an American copyright: but for that, anybody might pirate my books and pocket the profits (when there are any). The privilege of cashing vast sums in the case of a best-seller must therefore be acknowledged with thanks and with an adequate contribution for poor dear Uncle Sam in his always temporary difficulties.
