CHAPTER XXII
THE SHADOW INTERVENES
PROFESSOR ROGER BISCAYNE took immediate charge. The discovery of the remote-control machine was of the greatest moment now.
The details of the killings could be worked out later. For Silas Harshaw, dead, could no longer be a menace:
His work was ended; his fiendish schemes had been disclosed, made harmless forever.
The little model, with its complex contrivances, was a perplexing subject.
Biscayne had the paper that showed the plan, but as he compared the diagrams with the metal box, he saw discrepancies.
His knowledge of Silas Harshaw’s mechanical methods might avail, however. Roger Biscayne was the only man who could solve the intricacies of the device.
After several minutes of studying the device and the plans, Biscayne pressed various knobs with no result. The machine was not hooked up; but he seemed to be hoping for some action. None occurred.
Biscayne ended his experiments for the moment. He asked to see the papers that had been found within the hole behind the radiator.
