In fact, each moment she looked worse; her breast, that had been heaving with the stress, became still, and the pallor of her face grew like marble.
At these succeeding changes Mimi's fright grew, till it altogether mastered her.

She succeeded in controlling herself only to the extent that she did not scream.
Lady Arabella had followed Caswall, when he had recovered sufficiently to get up and walk--though stumblingly--in the direction of Castra Regis.
When Mimi was quite alone with Lilla and the need for effort had ceased, she felt weak and trembled.

In her own mind, she attributed it to a sudden change in the weather--it was momentarily becoming apparent that a storm was coming on.
She raised Lilla's head and laid it on her warm young breast, but all in vain.

The cold of the white features thrilled through her, and she utterly collapsed when it was borne in on her that Lilla had passed away.
The dusk gradually deepened and the shades of evening closed in, but Mimi did not seem to notice or to care.

She sat on the floor with her arms round the body of the girl whom she loved.
