returned to my study, I did my best to diagnose the case before me.
First, Sir John Harmon--his visit to the home of Franklin White.
Then--the deliberate murder. And, finally, young Margot Vernee, and her
confession. It was like the revolving whirl of a pinwheel, this series
of events: continuous and mystifying, but without beginning or end.
Surely, somewhere in the procession of horrors, there would be a loose
end to cling to. Some loose end that would eventually unravel the
pinwheel!

It was plainly not a medical affair, or at least only remotely so. The
thing was in proper hands, then, with Drake following it through. And I
had only to wait for his return.

He came at last, and closed the door of the room behind him. He stood
over me with something of a swagger.

"Dale, I have been looking into the records of this Michael Strange," he
said quietly. "They are interesting, those records. They go back some
ten years, when this fellow Strange was beginning his study of science.
And now Michael Strange is one of the greatest authorities in Paris on
the subject of mental telegraphy. He has gone into the study of human
thought with the same thoroughness that other scientists go into the
subject of radio telegraphy. He has written several books on the
subject."

Drake pulled a tiny black volume from the pocket of his coat and dropped
it on the table before me. With one hand he opened it to a place which
he had previously marked in pencil.

"Read it," he said significantly.

I looked at him in wonder, and then did as he ordered. What I read was
this:

"Mental telegraphy is a science, not a myth. It is a very real fact, a
very real power which can be developed only by careful research. To most
people it is merely a curiosity. They sit, for instance, in a crowded
room at some uninteresting lecture, and stare continually at the back of
some unsuspecting companion until that companion, by the power of
suggestion, turns suddenly around. Or they think heavily of a certain
person nearby, perhaps commanding him mentally to hum a certain popular
tune, until the victim, by the power of their will, suddenly fulfills
the order. To such persons, the science of mental telegraphy is merely
an amusement.

"And so it will be, until science has brought it to such a perfection
that these waves of thought can be broadcast--that they can be
transmitted through the ether precisely as
