"A thief like Marcus will get out of paying," he said, "and if he can stall you long enough to get the money you may whistle for your share. Besides, a fellow like that isn't really afraid of a charge of bigamy." Jean, curled up in a big arm-chair, looked up under her eyelashes at her father and laughed. "I had no intention of letting Marcus marry Lydia," she said coolly, "but I had to dangle something in front of his eyes, because he may serve me in quite another way." "How did he get those two slashes on his hand?" asked Mr. Briggerland suddenly. "Ask him," she said. "Marcus is getting a little troublesome. I thought he had learnt his lesson and had realised that I am not built for matrimony, especially for a hectic attachment to a man who gains his livelihood by cheating at cards." "Now, now, my dear," said her father. "Please don't be shocked," she mocked him. "You know as well as I do how Marcus lives." "The boy is very fond of you." "The boy is between thirty and thirty-six," she said tersely. "And he's not the kind of boy that I am particularly fond of. He is useful and may be more useful yet." She rose, stretched her arms and yawned. "I'm going up to my room to work on my story. You are watching for Mr. Jaggs?" "Work on what?" he said. "The story I am writing and which I think will create a sensation," she said calmly. "What's this?" asked Briggerland suspiciously. "A story? I didn't know you were writing that kind of Stuff." "There are lots of important things that you know nothing about, parent," she said and left him a little dazed. For once Jean was not deceiving him. A writing table had been put in her room and a thick pad of paper awaited her attention. She got into her kimono and with a little sigh sat down at the table and began to write. It was half-past two when she gathered up the sheets and read them over with a smile which was half contempt. She was on the point of getting into bed when she remembered that her father was keeping watch below. She put on her slippers and went downstairs and tapped gently at the door of the darkened dining-room. Almost immediately it was opened. "What did you want to tap for?" he grumbled. "You gave me a start." "I preferred tapping to being shot," she answered. "Have you heard anything or seen anybody?" The French windows of the dining-room were open, her father was wearing his coat and on his arm she saw by the reflected starlight from outside he carried a shot-gun. "Nothing," he said. "The old man hasn't come to-night." She nodded. "Somehow I didn't think he would," she said. "I don't see how I can shoot him without making a fuss." "Don't be silly," said Jean lightly. "Aren't the police well aware that an elderly gentleman has threatened my life, and would it be remarkable if seeing an ancient man prowl about this house you shot him on sight?" She bit her lips thoughtfully.
