Null felt that look in the very marrow of his bones. He bowed with servile submission, and took his leave.

In the meantime, Benjulia had satisfied himself that the embarrassment in Carmina's manner was merely attributable to shyness. She was now no longer an object even of momentary interest to him. He was ready to play with Zo--but not on condition of amusing himself with the child, in Carmina's presence. "I am waiting till Mrs. Gallilee returns," he said to her in his quietly indifferent way. "If you will excuse me, I'll go downstairs again; I won't intrude."

Her pale face flushed as she listened to him. Innocently supposing that she had made her little offer of hospitality in too cold a manner, she looked at Benjulia with a timid and troubled smile. "Pray wait here till my aunt comes back," she said. "Zo will amuse you, I'm sure." Zo seconded the invitation by hiding the stick, and laying hold again on her big friend's coattails.

He let the child drag him into the room, without noticing her. The silent questioning of his eyes had been again directed to Carmina, at the moment when she smiled.

His long and terrible experience made its own merciless discoveries, in the nervous movement of her eyelids and her lips. The poor girl, pleasing herself with the idea of having produced the right impression on him at last, had only succeeded in becoming an object of medical inquiry, pursued in secret. When he companionably took a chair by her side, and let Zo climb on his knee, he was privately regretting his cold reception of Mr. Null. Under certain conditions of nervous excitement, Carmina might furnish an interesting case. "If I had been commonly civil to that fawning idiot," he thought, "I might have been called into consultation."

They were all three seated--but there was no talk. Zo set the example.

"You haven't tickled me yet," she said. "Show Carmina how you do it."

He gravely operated on the back of Zo's neck; and his patient acknowledged the process with a wriggle and a scream. The performance being so far at an end, Zo called to the dog, and issued her orders once more.

"Now make Tinker kick his leg!"

Benjulia obeyed once again. The young tyrant was not satisfied yet.

"Now tickle Carmina!" she said.

He heard this without laughing: his fleshless lips never relaxed into a smile. To Carmina's unutterable embarrassment, he looked at her, when she laughed, with steadier attention than ever. Those coldly-inquiring eyes exercised some inscrutable influence over her. Now they made her angry; and now they frightened her. The silence that had fallen on them again, became an unendurable infliction. She burst into talk; she was loud and familiar--ashamed of her own boldness, and quite unable to control it. "You are very fond of Zo!" she said suddenly.

It was a perfectly commonplace remark--and yet, it seemed to perplex him.

"Am I?" he answered.

She went on. Against her own will, she persisted in speaking to him.

"And I'm sure Zo is fond of you."

He looked at Zo. "Are you fond of me?" he asked.

Zo, staring hard at him, got off his knee; retired to a little distance to think; and stood staring at him again.

He quietly repeated the question. Zo answered this time--as she had formerly answered Teresa in the Gardens. "I don't know."

He turned again to Carmina, in a slow, puzzled way. "I don't know either," he said.

Hearing the big man own that he was no wiser than herself, Zo returned to him--without, however, getting on his knee again. She clasped her chubby hands under the inspiration of a new idea. "Let's play at something," she said to Benjulia. "Do you know any games?"

He shook his head.

"Didn't you know any games, when you were only as big as me?"

"I have forgotten them."

"Haven't you got children?"

"No."

"Haven't you got a wife?"

"No."

"Haven't you got a friend?"

"No."

"Well, you _are_ a miserable chap!"

Thanks to Zo, Carmina's sense of nervous oppression burst its way into relief. She laughed loudly and wildly--she was on the verge of hysterics, when Benjulia's eyes, silently questioning her again, controlled her at the critical moment. Her laughter died away. But the exciting influence still possessed her; still forced her into the other alternative of saying something--she neither knew nor cared what.

"I couldn't live such a lonely life as yours," she said to him--so loudly and so confidently that even Zo noticed it.

"I couldn't live such a life either," he admitted, "but for one thing."

"And what is that?"

"Why are you so loud?" Zo interposed. "Do you think he's deaf?"

Benjulia made a sign, commanding the child to be silent--without turning towards her. He answered Carmina as if there had been no interruption.

"My medical studies," he said, "reconcile me to my life."

"Suppose you got tired of your studies?" she asked.

"I should never get tired of them."

"Suppose you couldn't study any more?"

"In that case I shouldn't live any more."

"Do you mean that it would kill you to leave off?"

"No."

"Then what do you mean?"

He laid his great soft fingers on her pulse. She shrank from his touch; he deliberately held her by the arm. "You're getting excited," he said.

"Never mind what I mean."

Zo, left unnoticed and not liking it, saw a chance of asserting herself.

"I know why Carmina's excited," she said. "The old woman's coming at six o'clock."

He paid no attention to the child; he persisted in keeping watch on Carmina. "Who is the woman?" he asked.

"The most lovable woman in the world," she cried; "my dear old nurse!"

She started up from the sofa, and pointed with theatrical exaggeration of gesture to the clock on the mantelpiece. "Look! it's only ten minutes to six. In ten minutes, I shall have my arms round Teresa's neck.

Don't look at me in that way! It's your fault if I'm excited. It's your dreadful eyes that do it. Come here, Zo! I want to give you a kiss." She seized on Zo with a roughness that startled the child, and looked wildly at Benjulia. "Ha! you don't understand loving and kissing, do you?
