A sudden look of understanding flashed into Isabel's face, and taking a quick step forward she laid her hand lightly on Tony's arm.
"You mean those men—those two men?" she whispered. "Why—are they outside? Have they found out where I am?"
Tony patted her hand. "There's nothing to be frightened about, Isabel," he said. "At least not for us."
She drew herself up proudly. "I'm not frightened," she said, "not a bit. I told you I should never be frightened again as long as I had you to help me." She took a long breath. "What are you going to do?" she asked. "Kill them?"
Tony laughed. "I think we ought to find out first what they want," he said. "There's a sort of prejudice in this country against massacring people at sight."
"I—I forgot we were in England," said Isabel apologetically. "I have heard father and the others talk so much about killing people, it doesn't seem nearly as serious to me as it ought to."
"Never mind," said Tony consolingly. "We all have our weak points." He leaned over and tipped off the ash of his cigar into the umbrella stand. "According to Bugg," he added, "our two friends have been hanging about outside the house ever since Tuesday."
Isabel opened her eyes. "Since Tuesday!" she repeated. "But why didn't you tell me?"
"I didn't want to worry you. I knew you would be quite safe with Bugg here, so I thought it was better to wait until I had made up my mind what to do." He paused. "Whoever these two beauties are it's quite evident that what they're really yearning for is another little private chat with you. At least it's difficult to see what else they can be after unless they are going in for a fresh air cure."
Isabel nodded her head. "It's me all right," she observed with some conviction.
