“I see,” responded Nick slowly, “that Hank Low could have done it.”

The reply disappointed Kerr, and he began to argue, but Nick interrupted him.

“Excuse me a moment, gentlemen,” he said.

He rose, and looked at Patsy, who withdrew with Nick to a corner of the room, and the two men whispered together a moment.

Then Patsy went out, and Nick returned to the table.

“Excuse me,” said Nick, again. “I don’t mean to interfere with your handling of the case. Mr. Kerr——”

“Oh, bless you!” exclaimed Kerr; “that’s what we all want. You do just what you think best, Mr. Carter.”

“Thank you. I was going to say that I had forgotten something, and sent my assistant out to look after it. Now, as to this time mark, it is very important. I can see that.”

“Of course,” said Kerr, encouraged by the great detective’s tone. “The testimony of the clerk cannot be doubted. Here is the sure testimony that Hank Low started for Judson’s room four minutes before the man fell from his window. It is known that Low left the hotel and drove away just before word was brought in that the man had fallen out. See?”

“Yes.”
