I ventured to raise my head cautiously, so as to gain a glimpse of the man, and was surprised to note the change in his face.
It was as though he had removed a mask.

Heretofore, always holding the winning hand, and able to sneer at opposition, he had always in my presence assumed an air of cold bravado, insolent and sarcastic; but now, baffled in his plans, checkmated by a girl, and believing himself unobserved, the gambler had given way to his true nature, both expression and manner exhibiting a temper beyond control.
I had but a moment in which to observe this new exhibit of the man's personality, for almost immediately Carver flung the door of the room open, and Kirby swung impatiently about to face the entrance.

Except for a possibility of thus attracting the attention of the newcomer, I was in no special danger of being detected by those within.
Nevertheless I sank lower, with eyes barely above the edge of the sill, eager to witness this meeting, and especially interested in gaining a first view of their prisoner.

Carver thrust her forward, but remained himself blocking the doorway.

I use the word thrust, for I noted the grip of his hand on her arm, yet in truth she instantly stepped forward herself, her bearing in no way devoid of pride and dignity, her head held erect, her eyes fearlessly seeking the face of Kirby.
