"It is too early to attempt any theorizing, Carnes. Let us confine ourselves to the known facts. Lieutenant Breslau was normal at midnight and was working in this room. Some time between then and seven this morning he underwent certain mental and physical changes which prevent him from telling us what he observed. During the same period, a hole was cut in the roof and things of great importance stolen. At the same time, all the glass in the laboratory became semi-opaque. The problem is to determine what connection there is between the three events. I will handle the scientific end here, but there is some outside work to be done, and that will be your share." * * * * * "Give your orders, Doctor," said the detective briefly. "To understand what I am driving at, I will have to tell you what has been stolen. Naturally this is highly confidential. Some rumors have leaked out as to my experiments with 'radite,' as I have named the new radium-containing disintegrating explosive on which I have been working, but no one short of the Secretary of War and the Chief of Ordnance and certain of their selected subordinates knows that my experiments have been successful and that the United States is in a position to manufacture radite in almost unlimited quantities from the pitchblende ore deposits of Wyoming and Nevada. The effects of radite will be catastrophic on the unfortunate victim on whom it is first used. The only thing left to do was to develop a gun from which radite shells could be fired with safety and precision.
