She looked up at him, surprised.

"It happened yesterday about this hour," he said.

"What happened?"

"Do you remember that you went home about three o'clock instead of waiting until this hour as usual?"

"Yes."

"Well, this is what occurred. I left the gallery at this same hour. Ahead of me descending the steps was a young girl who had just delivered a business letter to Mr. Quarren. As she set foot on the pavement a footman attached to an automobile drawn up across the street touched his cap to her and said: 'Beg pardon, Miss Vining, I am Mr. Sprowl's man. Mr. Sprowl would like to see you at the Café Cammargue. The car is waiting.'"

Miss Vining's colour faded; she stared at Dankmere with widening eyes, and he dropped his hands into his coat-pockets and returned her gaze.

"I don't understand you," she said in a low voice.

"Neither did the young girl addressed by the footman. Neither did I. But I was interested. So I said to the footman: 'Bring around your car. I shall have to explain about Miss Vining to Mr. Sprowl.'"

"What!" she said breathlessly.
