"No," he objected, as she tried to help him, "I will do the brain-work. Your part is to be feminine and rush briskly back and forth, offering me things I don't want. And at the last moment," he added gloomily, "you may tell me that there isn't a lemon in the place." He looked about with the hopelessness of a great artist facing the failure of his chef-d'œuvre. "I forgot the lemons."

She went across the room to a small closet. Even in the strain of the moment he observed the extraordinary grace and swiftness of her movements. She was very slender, very lithe, and she moved like a flash of light.

"Fancy my being caught without a lemon!" she scoffed, as she returned with the fruit. "Your brain-work stops abruptly sometimes, doesn't it?"

She handed him the lemons with a little gesture expressing amusement, triumph, and a dash of coquetry. Laurie's eyes glowed as he looked at her. For the second time, in her actual presence, a sharp thrill shot through him. Oh, if she were always like this!—gay, happy, without that incredible, unbelievable background of tragedy and mystery! He turned his mind resolutely from the intruding thought. This hour at least was hers and his. It should be prolonged to the last moment.

What he longed for was to hear her talk, but that way, he knew, lay disaster to the little supper in swift-returning memory. If she began to talk, the forbidden topic, now dormant, would uncoil its hideous length and hiss. He must hold her attention to other things.

He plunged at random into chatter. For the first time he told her about Bangs, his chum, and about Epstein, their manager; about their plays and their experiences in rehearsals and on the road. Being very young and slightly spoiled, he experienced some chagrin in the discovery that she seemed alike ignorant of the men and the plays. Worse yet, she seemed not even aware that she should have known who Bangs and Epstein were. She did not recall having heard the title of "The Black Pearl." She was not only unaware that "The Man Above" had broken all box-office records; she seemed unconscious that it had ever been written. Observing his artless surprise, she gravely explained. "I have been interested in other things," she reminded him.

The forbidden topic was stirring, stretching. To quiet it, Laurie leaped into the comedy scenes of "The Man Above." They delighted her. Her soft, delicious laughter moved him to give her bits from "The Black Pearl," and, following these, the big scenes from the latter play. This last effort followed the supper; and Laurie, now in his highest spirits, added to his effects by the use of a brilliant afghan, and by much raising and lowering of the light of the reading-lamp.

He was a fine mimic. He became by turns the star, the leading lady, the comedian, and the "heavy" of the big play. It was only when he had stopped for a moment's rest, and Doris demanded a description of the leading lady's gowns, now represented by the afghan, that his ingenuity failed.

"They're so beautiful that most people think I made them," he said, serenely. "But I didn't, really, so I can't give you any details, except that they're very close-fitting around the feet."

He was folding up the afghan as he spoke, and he stopped in the act, leaving one end dangling on the floor. From the street below the sound of a whistle came up to him, sharp and penetrating, repeating over and over the same musical phrase, the opening notes of the Fifth Symphony. At first he thought the notes were whistled by some casual passer-by. Then, glancing at the girl's face, he knew better. The sharp, recurrent phrase was a signal.
