“Why yes, of course. But what on earth are you doing out here, Jackson?” he demanded a little sharply.

“I was waiting for you, sir,” the man answered hurriedly. “I knew you’d gone out, Mr. Kane; and I knew I couldn’t miss you here, sir, when you came back, as you always come by the Avenue, sir. And, begging your pardon again, sir, would you mind if we didn’t stand here? You wouldn’t take offense, sir, if we went in by the garage driveway where we could be alone for a minute, sir?”

Billy Kane eyed the man critically. Jackson, immaculate in his livery, appeared to be quite himself; but Jackson at times had been known to possess a greater fondness for a bottle than was good for him.

“What is it, Jackson?” he demanded still more sharply. “Did Mr. Ellsworth send you here?”

“No, sir; he didn’t,” the man answered nervously. “But, if you please, Mr. Kane, sir, that is, if you don’t mind, sir, I’d rather wait until——”

“Very well, Jackson!” Billy Kane interrupted curtly. “I suppose you have a reason for your rather strange request. Come along, then, and I’ll listen to what you have to say.”

“Thank you, sir,” said the man earnestly.

They crossed the Avenue, passed down the cross street, turned the corner, and a moment later, entering by the garage driveway, gained the courtyard in the rear of the house. It was dark here, there were no lights showing from the back of the house itself or from the garage; and here, close to the private entrance to the “office” and library, Billy Kane halted.

“Well, Jackson, what’s it all about?” he inquired brusquely.

“If you please, Mr. Kane, sir”—the man’s voice had taken on a curious, quavering note—“don’t speak so loud. We—you—you might be heard, sir, from the servants’ entrance over there. I—Mr. Kane, sir—Mr. Ellsworth has been murdered, and the money, sir, and the rubies are gone.”
