Then it was as if her mind separated itself from the rest of her and began to run back along the path she had travelled with Knight since the hour of their first meeting. It ran looking on the ground, seeking and picking up things dropped and almost forgotten. Knight had not been pleased when the Countess de Santiago talked to him of their being together on the _Monarchic_. The Countess had seemed wishful to annoy him in some way. She had taken that way. They had known each other well and for a long time. They knew a good deal about each other's affairs. Sometimes one would say that the Countess still liked to annoy Knight, and he resented that. He had been unwilling to have her asked to Valley House for Easter, though he knew she longed to come. And Ruthven Smith! Knight had not wanted him. Could it possibly be on account of the blue diamond? Had Knight heard what _she_ had heard there at the dinner-table, and was he anxious about what might happen next? Hastily she flung a glance toward her husband. He was not looking at her, but it seemed--perhaps she imagined it--that his face had something of the same tense, strained expression she had caught on Charrington's. How odd, if it were true, that both should have that look. One would almost fancy they shared a secret trouble. But Annesley shook the idea away, as she would have shaken a hornet trying to sting. How dare she let such a disloyal fancy even cross the threshold of her mind? A secret between her husband and his servant--a secret concerning the blue diamond, which stabbed them both with the same prick of anxiety at the mention of the jewel! No sooner was the venomous thing dislodged than it crept back and settled close over her heart. For Knight's eyes turned to her, and in them was the look of a drowning man. Just for the fraction of a second she saw it. Then the curtain was drawn over his real self that had come to the window and signalled for help. He smiled a friendly smile, and took up the conversation with his right-hand neighbour. But he had hidden his soul too late. The message could not be taken back, and Annesley was sure that he, too, had heard the story Ruthven Smith had told so loudly to Lady Cartwright. The fact that he had lost his unruffled, nonchalant coolness even for a single instant warned Annesley that Knight must be desperately troubled. "He bought the diamond for me, knowing what it was," she told herself, "and knowing that it must have been stolen. Of course that's why he made me wear it where nobody could see. But who else knew besides the man who sold it to Knight? _Somebody_ must have known, and told Mr. Ruthven Smith. Perhaps the thief himself, hoping to be spared, and to get money from both sides. That is why Mr. Ruthven Smith accepted the invitation here, which I was so sure he would refuse. He has come because he thinks the Malindore diamond is in this house. That must be it! But how can he have found out that I am wearing it?"
