Melun intercepted the smile and scowled, and almost immediately moved back in a further endeavour to gain Lady Kathleen's side.
Westerham wandered aimlessly to a doorway, and there, following the immemorial privilege of bored young men at a dance or a crush, leant against the lintel and surveyed the scene before him with slightly tolerant amusement.
In half an hour or so the people had thinned a little; all the guests had made their bows, and some of them had even taken their departure.
It was then that Westerham noticed Lady Kathleen and the Prime Minister standing a little apart conversing earnestly in whispers, and at the same time doing their best not to attract attention.
From the corner of his eye Westerham saw Lady Kathleen flush once or twice and was conscious that the Prime Minister stabbed him two or three times with his shrewd old eyes.
Then Melun sauntered up to them, and succeeded in detaching Lady Kathleen from her father. They moved away together, and Westerham wondered what ill-begotten scheme Melun was furthering now. For another ten minutes, therefore, he hung idly in the doorway till he saw Melun come back alone and take the Prime Minister on one side. They were conversing rapidly, and Westerham could plainly see that Lord Penshurst was by no means pleased. There was, indeed, on his face an expression of cold rage such as Westerham had never seen on any man's face before. Melun, too, appeared a trifle disconcerted, and this was a joy to Westerham, for he was right in supposing that Melun had hoped to see fear rather than anger in Lord Penshurst's face.
Westerham was, however, not so interested in this conversation as he was in the finding of Lady Kathleen, so he moved across the room and through the doorway in search of the Premier's daughter.
The room beyond was crowded, and Westerham passed on to a third room in which there were fewer people. Still he could discern no signs of Lady Kathleen.
But just ahead of him he saw the dark entrance to what apparently was a landing. He moved towards this, and found himself suddenly face to face with her. She was sitting almost huddled up in a little chair at the foot of the staircase.
As she saw him approach she lifted up both her hands as though to thrust him away, and her face from deadly white flushed to a bright crimson.
