As George points out, the Vertigo character played by Kim Novak is Madeleine Elster, not Madeleine Astor. The latter is apparently a real-life personage who survived the Titanic. And don’t confuse either Madeleine with my beloved writing professor Madeleine, who is cool and is responsible for this. A madeleine can also be a delicious French pastries that looks like this.
And, oddly, Webster says a madeleine can also be "one that evokes a memory," which has interesting implications for Vertigo.
In any case, "Death Comes For the Blonde" has been fixed accordingly. Let's all try to keep them straight from here on out.
