"Mr. Jameson will see that you get home safely in a taxicab," he continued. "You can trust him as you would myself."

I can imagine circumstances under which I would have enjoyed escorting Inez to her home, but today was not one of the times. Yet she seemed so helpless, so grateful for everything we did for her that I did not need even the pressure of her little hand as she hurried into the apartment from the car with a hasty word of thanks.

"You will tell Mr. Kennedy—you will both be—so careful?" she hesitated before leaving me.

I assured her that we would, wondering what she might fear for us, as I drove away again. There did not happen to be any of the newspaper men about at the time, and I did not stop.

Back in the laboratory, I found Kennedy arranging something under the rug at the door as I came up the hall.

"Don't step there, Walter," he cautioned. "Step over the rug. I'm expecting visitors. How was she when she arrived home?"

I told him of her parting injunction.

"Not bad advice," he remarked. "I think there's a surprise back of those warnings. They weren't sent just for effect."

He had closed the door, and we were standing by the table, looking at the letters, when we heard a noise at the door.

It was Norton again.
