Roger's sudden gust of passion had taken her by surprise, filling her with a kind of terror of him.

Never before had he shown her that side of himself, and she had somehow taken it for granted that he would not prove a demanding lover.

He had been so diffident, so generous at the beginning, that she had been almost ashamed of the poor return which was all that she could make.

But now she was suddenly face to face with the fact that he was going to demand far more of her than she was able to give.
She had not realised how much propinquity adds fuel to love's fire.
Unknown, even to himself, Roger's passion had been gradually rising towards flood-tide.

Man being by nature a contradictory animal, the attitude assumed by his mother and cousin towards the woman who was to be his wife had seemed to fan rather than smother the flame.
All at once the curb had snapped.
