sent me up to the Milan Restaurant with a strange message. I was to
find Mr. Rosario and to see that he did not lunch there--to send him
away somewhere else, in fact. I didn't understand it, but of course
I went."

"And what happened?" she demanded.

He held his breath for a moment.

"I was to take a table just inside the restaurant," he explained,
"and to tell him directly he entered. I did exactly as I was told,
but it was too late. Rosario was stabbed as he was on the point of
entering the restaurant, within a few yards of where I was sitting."

She shivered a little, although her general expression was still
unchanged.

"You mean that he was murdered?"

"He was killed upon the spot," Arnold declared.

"By whom?"

He shook his head.

"No one knows. The man got away. I bought an evening paper as I came
along and I see they haven't arrested any one yet."

"Was there a quarrel?" she asked.
