I stayed awake to count the stars in the sky last night. Hence, I was a witness to a light that briefly appeared on one side of the lake ahead of us.
It was the first area we searched. And as there were fewer homes on that side of the lake we quickly found the only one occupied, and the source of the light.
The occupants are indeed the wife of the Purser and his children. She has set the light nightly in hopes that it would lead her husband to them. Though disappointed that “we” were not him, they are overjoyed to hear he is well.
She desires that he come join them in their flight from the city.
