There will be spoilers from the book here.
In the "Interlude", after chapter 12, we see
Bilquis (the Queen of Sheba)
as she stands on the sidewalk of Sunset Boulevard. She is picked up a passing limo, which belongs to the Technical Boy.
She and Technical Boy don't come to an agreement, so she jumps out of the limo and is then run over by it, several times, until her remains are no longer recognisable, and even they will be washed away by the rain.
Question is, why kill her at all? The beginning of the interlude indicates that a "cold war" was in progress by then, with a few seemingly unrelated and accidental deaths. Well, those were at least reported by the media.
Why kill her and leave no trace, and no message to the old gods?
And why kill her, of all gods, given she was largely unknown (no one mentions her in the novel) and mostly powerless?
