"You don't expect me to believe a fairy story like that?" Chief Meigs growled. "Here, let's get downstairs. We're wasting time."

"It's the gospel truth, officer," McGinity declared, vehemently; "but how he did it is a puzzle to me."

It was no puzzle to me. I had always considered LaRauche mad, and mad scientists work in a strange, mysterious way. His vanishing into the air, from the roof, might have a perfectly natural explanation. Having my own views, which I was not inclined at the moment to expose, for fear of further disgruntling the Chief, I said nothing.

Five minutes after the Chief and McGinity had gone downstairs, the reporter to search for LaRauche in the back-yard, while Chief Meigs reported the mysterious death of Orkins, and summoned medical aid for Mrs. LaRauche, by telephone, my attention was again attracted to the back window. This time it was by a bright glare of light.

Hurrying to the window, I was made speedily conscious of what was happening. LaRauche had, indeed, escaped from the house by way of the roof, in a manner yet to be revealed, and was now, apparently, making a quick getaway in his plane.

He had set off a magnesium flare. The small hangar and flying field were bathed in a weird and eerie silver-colored haze. His plane was in sight. Even at this distance, I caught the glint of its wings in the silver-colored light as it taxied across the field. With a roar, it shot upward, and was lost in the blackness of the night.

McGinity had heard the noise of the take-off, and came running up, to learn from me, and make sure his speculations, that LaRauche had really vanished from the roof, as if by magic, and was now escaping in his plane. I assured him on these two points very firmly and quickly.

And while he hurriedly retraced his steps downstairs, to report to Meigs, I again turned my attention to Mrs. LaRauche, whose mind, although still in confusion, was slowly clearing.

Later, we were to hear some very remarkable things from her.
