Frobisher’s eyes gleamed. He had been thinking much the same thing. Followed by Lefroy, he repaired to the smoking-room and proffered his hospitality. For some time the Count smoked and drank in silence, waiting for a lead from his host. There was bound to be some kind of explanation between them, and Lefroy preferred the lead to come from the other. "Silence is golden," Frobisher said, with one of his sudden grins. "In this case," the other said. "Perhaps you would like to deal the first hand. I shall sit tight for the present." "I fancy it is my play," Frobisher said thoughtfully. "Fate and the other players push us a long way off our line of policy sometimes. For instance, I never imagined that I should be dragged into an offensive and defensive alliance with you. But for the present it is absolutely necessary. We must get that precious gew-gew——" "Call it the sacred Blue Stone of Ghan and have done with it," Lefroy growled. "Very well, though it is hardly diplomacy. Mrs. Benstein came here wearing the Blue Stone. You found it out quite by accident, and it was your game to prevent me from knowing. You tried very hard, but you were a little too much taken by surprise, especially when the Shan was announced." "That was a very awkward moment for me," Lefroy admitted. "It was. Directly you came in here I guessed exactly what had happened. As a matter of fact, I had not the least intention of your coming here to-night, indeed I didn’t know you were coming. As a matter of fact, also, my wife cordially dislikes you, and I suppose she only asked you out of compliment to me." "We’ll let that pass," Lefroy said. "I was startled when Mrs. Benstein dropped her mask and the Blue Stone stood revealed. Of course, I knew that the stone was pledged to Benstein, and that Mrs. Benstein having it was natural enough. The doting old fool had been wheedled out of it for the evening. But I didn’t know that you knew that, and I was most anxious to keep the information from you. But directly I came face to face with you here, I knew that you had some deep scheme, and that you guessed that I had got wind of it. I have worked that out." Frobisher smoked and sipped his brandy with infinite relish. "I always like to study a subtle mind, Count," he said. "Will you explain your meaning?" "Certainly, especially as I shall lose nothing by so doing. Why did you get your wife to ask that woman here at all? I knew you had to use something like force to bring it about. You did it because you knew where the Blue Stone was. You advised Mrs. Benstein as to her dress, you gave her hints on that head. You were quite aware of the extent of Benstein’s senile devotion to his wife. And you calculated that if she adopted the ruby suggestion she would borrow the Blue Stone."
