t his footing, and fell heavily on
the pavement. It seemed to him that Mr. Bessel leapt over him as he
fell. When he looked again Mr. Bessel had vanished, and a policeman
and a number of garden porters and salesmen were rushing past towards
Long Acre in hot pursuit.

With the assistance of several passers-by--for the whole street was
speedily alive with running people--Mr. Vincey struggled to his feet.
He at once became the centre of a crowd greedy to see his injury. A
multitude of voices competed to reassure him of his safety, and then to
tell him of the behaviour of the madman, as they regarded Mr. Bessel.
He had suddenly appeared in the middle of the market screaming "Life!
Life!" striking left and right with a blood-stained walking-stick, and
dancing and shouting with laughter at each successful blow. A lad and
two women had broken heads, and he had smashed a man's wrist; a little
child had been knocked insensible, and for a time he had driven every
one before him, so furious and resolute had his behaviour been. Then
he made a raid upon a coffee stall, hurled its paraffin flare through
the window of the post office, and fled laughing, after stunning the

Mr. Vincey's first impulse was naturally to join in the pursuit of his
friend, in order if possible to save him from the violence of the
indignant people. But his action was slow, the blow had half stunned
him, and while this was still no more than a resolution came the news,
shouted through the crowd, that Mr. Bessel had eluded his pursuers. At
first Mr. Vincey could scarcely credit this, but the universality of
the report, and presently the dignified return of two futile policemen,
convinced him. After some aimless inquiries he returned towards Staple
Inn, padding a handkerchief to a now very painful nose.

He was angry and astonished and perplexed. It appeared to him
indisputable that Mr. Bessel must have gone violently mad in the midst
of his experiment in thought transference, but why that should make him
appear with a sad white face in Mr. Vincey's dreams seemed a problem
beyond solution. He racked his brains in vain to explain this. It
seemed to him at last that not simply Mr. Bessel, but the order of
things must be insane. But he could think of nothing to do. He shut
himself carefully into his room, lit his fire--it was a gas fire with
asbestos bricks--and, fearing fresh dreams if
