She tried to determine where the echoes were coming from, but they seemed all around.

Those weird echoes had come as the laugh of a ghost!

The echoes from that hadn't even come close to dying down.

Only the echoes from the torch-lit halls came back to him.

From far below came the dim echoes of an enormous splash.

Listen to how the echoes come back from all the walls at practically the same time.

From a long way off echoes came to him, words without meaning, questions without answers.

I had my feet on the ground as the echoes came back.

To their ears came the last echoes of a strange, weird laugh.
