He continued what Mr. Ridding, watching the group of young people, called sulkily to himself his rigmarole, but continued more abstractedly. He also was watching the Annas and the experts. The young men were evidently in the highest spirits, and were walking round the Annas admiring their get-up and expressing their admiration in laughter and exclamations. One would have thought they had known each other all their lives. The twins were wreathed in smiles. They looked as pleased, Mr. Twist thought, as cats that are being stroked. Almost he could hear them purring. He glanced helplessly across to where Mrs. Bilton sat, as he had told her, bent pen in hand over the ledger. She didn't move. It was true he had told her to sit like that, but hadn't the woman any imagination? What she ought to do now was to bustle forward and take that laughing group in charge. "As I was telling you--" resumed Mr. Twist, returning with an effort to Mr. Ridding, only to find his eyes fixed on the young people and catch an unmistakably thwarted look in his face. In a flash Mr. Twist realized what he had come for,--it was solely to see and talk to the twins. He must have noticed them at the Cosmopolitan, and come out just for them. Just for that. "Unprincipled old scoundrel," said Mr. Twist under his breath, his ears flaming. Aloud he said, "As I was telling you--" and went on distractedly with his rigmarole. Then some more people came in. They had motored, but the noise the experts were making had drowned the sound of their arrival. Mr. Ridding and Mr. Twist, both occupied in glowering at the group in the middle of the room, were made aware of their presence by Anna-Felicitas suddenly dropping the pencil and tablets she had been provided with for writing down orders and taking an uncertain and obviously timid step forward. They both looked round in the direction of her reluctant step, and saw a man and two women standing on the threshold. Mr. Twist, of course, didn't know them; he hardly knew anybody, even by sight. But Mr. Ridding did. That is, he knew them well by sight and had carefully avoided knowing them any other way, for they were Germans.
