believed Strange would ignore you, because, after all, you
are not a Scotland Yard man. Thank God I had the sense to follow
Margot--to trail her here--and get here soon enough."

And so ended the horrible series of events that began with Sir John
Harmon's chance visit to my study. As for Harmon, he was later cleared
of all guilt, upon the charred evidence in Michael Strange's house in
Mate Lane. The girl, I believe, has left London, where she can be as far

will never rest entirely easy until the slow process of time again
heals the protective layer."--From "Beyond the Heaviside Layer."

Over a year has passed since I wrote those lines. When they were written
the hole which Jim Carpenter had burned with his battery of infra-red
lamps through the heaviside layer, that hollow sphere of invisible
semi-plastic organic matter which encloses the world as a nutshell does
a kernel, was gradually filling in as he had predicted it would: every
one thought that in another ten years the world would be safely enclosed
again in its protective layer as it had been since the dawn of time.
There were some adventurous spirits who deplored this fact, as it would
effectually bar interplanetary travel, for Hadley had proved with his
life that no space flyer could force its way through the fifty miles of
almost solid material which barred the road to space, but t
