“Past three, by Jove! There’s only one person would ring me up at this time of night. It’s Maude. Perhaps it is important; you had better stay a moment,” he said.

Stent stayed. Farloe took off the receiver, and listened for a little time to the voice at the other end. Although Stent could not distinguish the words, now and then he caught an inflection that he recognised. Farloe’s conjecture was right. It was Mrs Saxton who had rung him up.

Then Stent heard the young man’s reply.

“Hold on a minute, he is here. He was just going when you rang.”

He beckoned to Stent. “She wanted me to send you word that she wished to meet you. You can arrange it with her yourself.”

They talked for a few seconds. At one of her remarks Stent laughed heartily. He turned to Farloe.

“She is suggesting that we don’t make it the Knightsbridge Tube Station.” Then he turned again to the instrument.

“That was a capital move of yours; your brother has just been telling me about it. Really, I think just now it might be as convenient a place as any; they would never think you would have the cheek to go there again so soon. Let us meet at the old spot. That’s safe enough. To-morrow then. All right. Good-bye.”
