If you just asked me a question about my default icon and I linked you here –

Hi! Yeah, I loved this icon too, and I asked the person I saw using it if I could take it too. They told me what it was from, but I promptly forgot it. And then forgot it the next couple times someone else asked and then another someone else answered for me.

So when frequentmouse answered yet again here, I decided to copy the answer and paste it here:

Gaudy Night by Dorothy Sayers; the conversation about ducks breaks a rather fraught verbal dance around Lord Peter's feelings about Harriet Vane, taking place in a punt on the Cher.

Huzzah!
