“To me?” said Flora.

“Mademoiselle, you are engaged to Captain Ralph Paton. If any one is in his confidence, you are. I beg you, most earnestly, if you know of his whereabouts, to persuade him to come forward. One little minute”—as Flora raised her head to speak—“say nothing till you have well reflected. Mademoiselle, his position grows daily more dangerous. If he had come forward at once, no matter how damning the facts, he might have had a chance of explaining them away. But this silence—this flight—what can it mean? Surely only one thing, knowledge of guilt. Mademoiselle, if you really believe in his innocence, persuade him to come forward before it is too late.”

Flora’s face had gone very white.

“Too late!” she repeated, very low.

Poirot leant forward, looking at her.

“See now, mademoiselle,” he said very gently, “it is Papa Poirot who asks you this. The old Papa Poirot who has much knowledge and much experience. I would not seek to entrap you, mademoiselle. Will you not trust me—and tell me where Ralph Paton is hiding?”

The girl rose, and stood facing him.

“M. Poirot,” she said in a clear voice, “I swear to you—swear solemnly—that I have no idea where Ralph is, and that I have neither seen him nor heard from him either on the day of—of the murder, or since.”

She sat down again. Poirot gazed at her in silence for a minute or two, then he brought his hand down on the table with a sharp rap.

Bien! That is that,” he said. His face hardened. “Now I appeal to these others who sit round this table, Mrs. Ackroyd, Major Blunt, Dr. Sheppard, Mr. Raymond. You are all friends and intimates of the missing man. If you know where Ralph Paton is hiding, speak out.”
