At a corner near the center of the Google Maps image above there is a strange plaque celebrating a literary moment in history that could not have possibly seemed worthy of celebration when it occurred. Two famous writers visited a foreign city together, intending to rekindle their troubled and illicit romance, but the getaway went badly. One of the writers wanted to leave, but the other did not want this to happen, and shot the first writer. The wound was not fatal, except to their friendship.
Who are these two writers, and what is the name of this city? Once again, I hope you will venture a guess, and to keep anyone from giving the answer away (I know at least a few of you will guess it!) I will not publish any comments to this post until I reveal the answer tomorrow. Here are a few clues:
• Both writers are greatly respected today, but neither are widely read by the general public.
• A humorous reference to this couple's difficult love affair can be found in a Bob Dylan song.
• One of these writers has a strong presence here on Literary Kicks.
That's all the help you'll get! Please post your guess as a comment below, and I'll publish all the comments and post a longer explanation tomorrow.
UPDATE: The answer to this question is here.
