handkerchief, into the hole and covered it up.

Jennings was clearly puzzled. He had seen some one rush in, but
the conservatory was apparently empty. He had just turned to go
out when he saw a palm move. There was a face! He made a dive for
it and in a moment both he and the crook were rolling over and
over.

. . . . . . .

Kennedy and the Secret Service men were talking earnestly when
they heard the cry for help and the scuffle. They rushed out and
into the conservatory in time to see the crook, who had broken
away, knock out Jennings. He sprang to his feet and darted away.

Kennedy's mind was working rapidly. Had the man been after the
other model? The detectives went after him. But Craig went for the
torpedo. As he looked in the tank, it was gone! He turned and
followed the crook.

I was still in the garden with Elaine and Aunt Josephine when I
heard sounds of a struggle and a moment later a man emerged
through the window of the conservatory followed by two other men.
I went for him, but he managed to elude me and dashed for the wall
in the back of the garden. The Secret Service men fired at him but
he kept on. A moment later Craig came through the window.

"Did any of you take the torpedo?" he asked.

"No," replied Elaine, "we left it just as you had it."
