“Who was it?”

“I couldn’t quite catch the name, sir. It sounded like Shuffle—something.”

“Shuttleworth!” I cried. “Did he leave any message?”

“No, sir. He merely asked if you were in—that’s all.”

As Sylvia was in London, perhaps Shuttleworth was in town also, I reflected. Yet she had cleverly made her escape—in order to avoid being questioned. Her secret was a guilty one!

I called up Jack, who answered cheerily as usual.

“You didn’t ring me up about one o’clock this morning, did you?” I inquired.

“No. Why?” he asked.

“Oh—well, nothing,” I said. “I thought perhaps it might have been you—that’s all. What time shall you be in at White’s?”

“About four. Will you be there?”
