"Not yet, but the key to it is in this report of yours. Do you know what
has become of the junior clerk, Small?"

"No. He left the firm to go abroad, I understand."

"I should like to have asked him whether John Delverton, the invalid
partner, had seemed worried when he was last at the office."

"He was not at the office that day. I asked that question, and Southey is
certain upon the point."

"Farrell might have left early to see him."

"Of course, we might question Kellner," I suggested.

"Kellner has the interests of the firm at heart, and is not personally
connected with the affair. I don't suppose he will be pleased to have the
old mystery raked up; naturally he will fear damage to the firm. I do not
think he would be inclined to help us in any way, and I can imagine his
being angry with Delverton for mentioning the affair to me."

"Still, I think there is something that wants explaining about Mr.
Kellner," said Zena, "You evidently thought so too, Murray, since you
made such minute inquiries about him."

"I do not think there is anything against him," I answered.

"I am not very interested in Kellner's past," said the professor, "and as
we cannot get hold of Small we must do a little guessing."
