Quest showed him the open door and the marks of footsteps around where he had picked up the handkerchief.
"Now," he said, "what has become of your man Craig, and what has become of my assistant Lenora ?" "Perhaps we had better search the house," the Professor suggested.

"Craig?
My dear Mr.Quest, you little know--" "Where is he, then ?" Quest interrupted.
The Professor could do nothing but look around him a little vaguely.
Together they went back to the house and searched it without result.

Then they returned once more to the garage.
"I am going back," Quest announced.

"My only chance is the wireless.

If Lenora is alive or at liberty, she will communicate with me." "May I come, too ?" the Professor asked timidly.
