The mask of indifference had fallen and her checks were wet.

After a moment the mask fell out of his hand and into his lap.

A golden mask had fallen from the wall and thudded to the floor behind them.

Make up your mind to it - when the armies come, the mask will fall.

The masks of captain and first officer fell into place.

Then the mask slipped from his grasp and fell to the floor.

He looked up, and it was as though a mask had fallen away.

The masks had actually fallen due to some electrical fault, not a pressure failure.

When the door had finally closed behind the two men, the mask fell from Chauvelin's face.

Just like that his mask fell away, and he was Azoth once more.
