The professor shook her hard. "How dare you say that!" he exclaimed furiously. "I do not know who killed my cousin. But I more than suspect Arnold Calvert. I spoke to your mistress. She can prove much, and she will. The money--the money----" Bocaros convulsively opened and shut his hand. "I must have that money." "Well," said Emily, rising to go, "you hear me. I'm going to Fanny for a week, and I shall expect to hear from you. I'll marry you as soon as you can get the licence, and I'll behave as I like." "No," said Bocaros savagely. "Yes," she retorted. "Don't you think I'm a fool, baron, because I'm not. I can play my own game. If you don't marry me, I'll tell the police what I told you." "You'll ruin your mistress if you do." "She's ruined me," retorted Miss Doon, her hand on the door, "and I always pay my debts. I don't know what game you are playing, but, as I say, I can play my own." Bocaros made a dash at her, but she was too quick for him. With wonderful dexterity she whipped through the door, and was outside, walking rapidly away, before he had time to recover from his rage. He went back to his chair, and flung himself down with a curse. Mrs. Fane had evidently played him false, since she had behaved so with her maid. Bocaros had thought she was in his power, but the dismissal of Emily showed that Mrs. Fane was quite prepared to make the matter public. If this were the case, she might not be ready to assist him in punishing Arnold, since she would not care to be mixed up with a murder case. And the whole chance of getting the money out of Calvert lay in the fact of the matter being kept quiet. From Arnold's demeanour Bocaros did not think he was guilty, but he fancied he could frighten him, and so gain his ends. But if Mrs. Fane made the whole affair public, Calvert might--and probably would--face the worst. No money would be forthcoming then. So Bocaros sat gnawing his fingers, filled with perplexing thoughts and looking old and worn. "I'll see Jasher," he said to himself, "and tell him all. He may see a way out of the matter. I'll write to him to come here this evening." So saying, the professor sat down and wrote a letter, which he directed to the Private Inquiry-Office. He closed the envelope and stamped it, and then returned to his seat. Hardly had he sat down when a sharp knock came to the door. Glancing through the window, the professor saw Calvert and Tracey on the step. Here was the very man he was wishing to circumvent putting his head into the lion's mouth. But Bocaros did not like the presence of Tracey, as the American was so sharp. He could deal with Arnold, but Tracey was beyond him. At first he decided to remain quiet in the hope that the two men would depart, but his curiosity got the better of his prudence, and he opened the door, to be met by the smile of Luther.
