his side.

"Upstairs," Quest repeated firmly. "If you utter a cry I shall shoot you."

Craig turned slowly round and obeyed. He mounted the stairs with reluctant
footsteps, followed by Quest.

"Through the door to your right," the latter directed. "That's right! Now
sit down in that chair facing me."

Quest closed the door carefully. Craig sat where he had been ordered, his
fingers gripping the arms of the chair. In his eyes shone the furtive,
terrified light of the trapped criminal.

Quest looked him over a little scornfully. It was queer that a man with
apparently so little nerve should have the art and the daring to plan such
exploits.

"What do you want with me?" Craig asked doggedly.

"First of all," Quest replied, "I want to know what you have done with my
assistant, the girl whom you carried off from the Professor's garage."

Craig shook his head.

"I know nothing about her."

"She locked you in the garage," Quest continued, "and sent for me. When I
arrived, I found the garage door open, Lenora gone and you a fugitive."

Bewilderment struggled for a moment with blank terror in Craig's
expression.

"How do you know that she locked me in the garage?"

Quest smiled, stretched out his right arm and his long fingers played
softly with the pocket wireless.

"In just the same way," he explained, "that I am sending her this message
at the present moment--a message which she will receive and understand
wherever she is hidden. Would you like to know what I am telling her?"

The man shivered. His eyes, as though fascinated, watched the little
instrument.

"I am saying this, Craig," Quest continued. "Craig is here and in my
power. He is sitting within a few feet of me and will not leave this room
alive until he has told me your whereabouts. Keep up your courage, Lenora.
You shall be free in an hour."

The trapped man looked away from the instrument into Quest's face. There
was a momentary flicker of something that might have passed for courage in
his tone.

"Mr. Quest," he said, "you are a wonderful man, but there are limits to
your power. You can tear my tongue from my mouth but you cannot force me
to speak a word."

Quest leaned a little further forward in his chair, his gaze became more
concentrated.

"That is where you are wrong, Craig. That is where you make a mistake. In
a very few minutes you will be telling me all the secrets of your heart."

Craig shivered, drew back a little in his chair,
