She nodded slowly, but her eyes reverted to the woman crouching in the chair, face buried in her brilliantly jewelled hands.  Portlaw and Tressilvain were also staring at her.

“You’d better go to bed, Helen,” said Malcourt coolly; and turned on his heel, lighting a cigarette.

A little later the Tressilvains and Shiela started across the lawn to their own apartments, and Malcourt went with them to hold an umbrella over his wife.

In the lower hall they separated with scarcely a word, but Malcourt detained his brother-in-law by a significant touch on the arm, and drew him into the library.

“So you’re leaving to-morrow?” he asked.

“What?” said Tressilvain.

“I say that I understand you and Helen are leaving us to-morrow.”

“I had not thought of leaving,” said Tressilvain.

“Think again,” suggested Malcourt.

“What do you mean?”

Malcourt walked up very close and looked him in the face.

“Must I explain?” he asked contemptuously.  “I will if you like—­you clumsy card-slipping, ace-pricking blackguard!...  The station-wagon will be ready at seven.  See that you are, too.  Now go and tell my sister.  It may reconcile her to various ideas of mine.”

And he turned and, walking to a leather-covered chair drawn up beside the library table, seated himself and opened a heavy book.

Tressilvain stood absolutely still, his close-set eyes fairly starting from his face, in which not a vestige of colour now remained; and when at length he left the room he left so noiselessly that Malcourt did not hear him.  However, Malcourt happened to be very intent upon his own train of thought, so absorbed, in fact, that it was a long while before he looked up and around, as though somebody had suddenly spoken his name.

But it was only the voice which had sounded so often and familiarly in his ears; and he smiled and inclined his graceful head to listen, folding his hands under his chin.

He seemed very young and boyish, there, leaning both elbows on the library table, head bent expectantly as he listened, or lifted when he, in turn, spoke aloud.  And sometimes he spoke gravely, argumentatively, sometimes almost flippantly, and once or twice his laugh rang out through the empty room.

In the forest a heavy wind had risen; somewhere outside a door or shutter banged persistently.  He did not hear it, but Shiela, sleepless in her room above, laid down Hamil’s book; then, thinking it might be the outer door left carelessly unlocked, descended the stairs with lighted candle.  Passing the library and hearing voices she halted, astonished to see her husband there alone; and as she stood, perplexed and disturbed, he spoke as though answering a question.  But there was no one there who could have asked it; the room was empty save for that solitary figure.  Something in his voice terrified her—­in the uncanny monologue which meant nothing to her—­in his curiously altered laugh—­in his intent listening attitude.  It was not the first time she had seen him this way.
