But Sassoon had the unpleasant patience of a mountain-lion and its dogged persistence, and, hiding himself on Black Cap, he made certain one day of what he had long been convinced--that Nan was meeting de Spain. The day after she had mentioned Black Cap to her lover, Nan rode over to Calabasas to get a bridle mended. Galloping back, she encountered Sassoon just inside the Gap. Nan so detested him that she never spoke when she could avoid it. On his part he pretended not to see her as she passed. When she reached home she found her Uncle Duke and Gale standing in front of the fireplace in the living-room. The two appeared from their manner to have been in a heated discussion, one that had stopped suddenly on her appearance. Both looked at Nan. The expression on their faces forewarned her. She threw her quirt on the table, drew off her riding-gloves, and began to unpin her hat; but she knew a storm was impending. Gale had been made for a long time to know that he was an unwelcome visitor, and Nan's greeting of him was the merest contemptuous nod. "Well, uncle," she said, glancing at Duke, "I'm late again. Have you had supper?" Duke always spoke curtly; to-night his heavy voice was as sharp as an axe. "Been late a good deal lately." Nan laid her hat on the table and, glancing composedly from one suspicious face to the other, put her hands up to rearrange her hair. "I'm going to try to do better. I'll go out and get my supper if you've had yours." She started toward the dining-room. "Hold on!" Nan paused at her uncle's ferocious command. She looked at him either really or feignedly surprised, her expression changing to one of indignation, and waited for him to speak. Since he did no more than glare angrily at her, Nan lifted her brows a little. "What do you want, uncle?" "Where did you go this afternoon?" "Over to Calabasas," she answered innocently. "Who'd you meet there?" Duke's tone snapped with anger. He was working himself into a fury, but Nan saw it must be faced. "The same people I usually meet--why?" "Did you meet Henry de Spain there this afternoon?" Nan looked squarely at her cousin and returned his triumphant expression defiantly before she turned her eyes on her uncle. "No," she said collectedly. "Why?" "Do you deny it?" he thundered. "Yes, I deny it. Why?" "Did you see de Spain at Calabasas this afternoon?" "No." "See him anywhere else?" "No, I did not. What do you mean? What," demanded his niece with spirit, "do you want to know? What are you trying to find out?" Duke turned in his rage on Gale. "There! You hear that--what have you got to say now?" he demanded with an abusive oath. Gale, who had been hardly able to refrain from breaking in, answered fast. "What have I got to say?" he roared. "I say I know what I'm talking about. I say she's lying, Duke."
