"If you'll hold the object where I told you," Quest replied, "I can see
it. I promise you that. There, that's right. Hold it steady. I've got the
focus of it now. Say, French, where did you say that was found?"

"Just outside the Professor's back gates," French grunted, "but you're not
kidding me--"

"It's a finger from the Professor's skeleton you've got there," Quest
interrupted.

"How the blazes did you guess that?" the Inspector demanded.

"I'm not kidding," Quest assured him. "I've got a phototelesme at work
here. I've seen the bone all right. French, this is interesting. I must
think it over."

Quest hung up the receiver and rang off. Then he turned towards his two
assistants.

"Another finger from the Professor's skeleton," he announced, "has been
found just outside his grounds. What do you suppose that means?"

"Craig," Lenora declared confidently.

"Craig on your life," Laura echoed. "Say, Mr. Quest, I've got an idea."

Quest nodded.

"Get right ahead with it."
