Faint Knockings behind every door.
"Sympathetic Magic"
Paul Cameron Brown
Now that he had actually come, as she had written him, as she had not believed he would come, she felt cold and hot all at once with sudden irregular Knockings of her heart within.
"The Salamander"
Owen Johnson
The wooden screws could be heard creaking; dull Knockings resounded; sometimes a sharp cry would suddenly pierce the air.
"Salammbo"
Gustave Flaubert
