Battle’s manner was easy and pleasant enough. He even refrained from looking at her, and the fact that he did so made her vaguely uneasy.

“It’s more difficult than you think,” she said at last. “He did me a great service once——”

Battle interrupted her.

“Before you go any further, Mrs. Revel, I’d just like to say something. Last night, after you and Mr. Eversleigh had gone to bed, Mr. Cade told me all about the letters and the man who was killed in your house.”

“He did?” gasped Virginia.

“Yes, and very wisely too. It clears up a lot of misunderstanding. There’s only one thing he didn’t tell me—how long he had known you. Now I’ve a little idea of my own about that. You shall tell me if I’m right or wrong. I think that the day he came to your house in Pont Street was the first time you had ever seen him. Ah! I see I’m right. It was so.”

Virginia said nothing. For the first time she felt afraid of this stolid man with the expressionless face. She understood what Anthony had meant when he said there were no flies on Superintendent Battle.

“Has he ever told you anything about his life?” the detective continued. “Before he was in South Africa, I mean. Canada? Or before that, the Sudan? Or about his boyhood?”

Virginia merely shook her head.

“And yet I’d bet he’s got something worth telling. You can’t mistake the face of a man who’s led a life of daring and adventure. He could tell you some interesting tales if he cared to.”
