Fans of gothic writer Edgar Allan Poe are planning what could be a final vigil in Baltimore to watch for a mysterious visitor who has failed to appear for two years after decades of visiting the author's grave on his birthday.

The rose and cognac tributes of an anonymous man in black _ dubbed the "Poe Toaster" _ are thought to date to at least the 1940s. Notes left with the tributes indicate the tradition passed to a new generation in the 1990s.

But the visitor hasn't appeared since 2009. Last year's vigil attracted impostors, including a man who arrived in a limo.

Poe House and Museum Curator Jeff Jerome says he'll wait one last time Wednesday night before calling an end to the tradition.
