"You know this police agent. You also are a police agent, though so much greater. Therefore you whisper just one little word in the ear of your friend the police agent, and he will not bother Madame Holymead again. I think you could do this. And if you need money to give to the police agent, why, I have brought some." She fumbled nervously at her hand-bag. "Stay," said Crewe. "What you ask is impossible. I have nothing whatever to do with Scotland Yard. I could not interfere in their inquiries, even if I wished to. They would only laugh at me." Gabrielle's dark eyes showed her disappointment, but she made one more effort to gain her end. She leant nearer to Crewe, and laid a persuasive hand on his arm. "If you would only make the effort," she said coaxingly, "my beautiful Madame Holymead would be for ever grateful." "Mademoiselle, once more I repeat that what you ask is impossible," returned Crewe decisively. "I repeat, I cannot see why Mrs. Holymead should object to answering a few questions the police wish to ask her. She is too sensitive about such a trifle." Gabrielle shrugged her shoulders slightly in tacit recognition of the fact that the man in front of her was too shrewd to be deceived by subterfuge. "There is another reason, monsieur," she whispered. "You had better tell it to me." "If you had been a woman you would have guessed. The great judge who was killed was in his spare moments what you call a gallant--he did love my sex. In France this would not matter, but in England they think much of it--so very much. Madame Holymead is frightened for fear the least breath of scandal should attach to her name, if the world knew that the police agent had visited her house on such an errand. Madame is innocent--it is not necessary to assure you of that; but the prudish dames of England are censorious." "The Scotland Yard people are not likely to disclose anything about it," said Crewe. "That may be so, but these things come out," retorted Gabrielle. "Monsieur," she added, after a pause, and speaking in a low tone, "I know that you can do much--very much--if you will, and can stop Madame Holymead from being worried. Would you do so if you were told who the murderer was--I mean he who did really kill the great judge?" Crewe was genuinely surprised, but his control over his features was so complete that he did not betray it. "Do you know who Sir Horace Fewbanks's murderer is?" he asked, in quiet even tones. "Monsieur, I do. I will tell you the whole story in secret--how do you say?--in confidence, if you promise me you will help Madame Holymead as I have asked you." "I cannot enter into a bargain like that," rejoined Crewe. "I do not know whether Mrs. Holymead may not be implicated--concerned--in what you say." "Monsieur, she is not!" flashed Gabrielle indignantly. "She knows nothing about it. What I have to tell you concerns myself alone."
