From the window, he looked on to an identical tenement, curtains closed, windows darkened.

The chairs were large and well padded, the windows darkened against any threat of accidental observation.

The windows and the glass partition darkened until they were opaque.

The windows in the suite had darkened to eliminate the worst of the sun's glare.

As he looked, a lighted window darkened from someone moving past it inside.

The bright window darkened and it was night.

The windows of the chamber where he lay, I darkened last.

Right there was the house he had just left, all windows darkened as if everyone inside were fast asleep.

With the windows of the vehicle darkened, it was hard to tell even the general direction they were now taking.

A sudden rumbling shook the building and the windows darkened as a ship settled in the street outside.
