They
had
tuned
out
on
the
escalator
rays,
but
continued
on
still
invisible--for
the
disc
hung
above
them
in
plain
view
and
it
would
have
been
suicide
to
let
themselves
be
seen.
Even
so,
Kendrick
soon
began
to
have
an
uneasy
feeling
of
being
followed.
He
looked
around
from
time
to
time,
but
could
see
nothing.
Were
some
of
those
invisible
little
creatures
on
their
trail?
He
said
nothing
to
Marjorie
of
his
anxiety,
but
presently
she
too
began
glancing
backward
uneasily,
every
few
steps.
"They
are
near
us!"
she
said
at
length,
in
a
whisper.
"I
can
sense
them."
It
was
more
than
sense,
they
soon
discovered.
Little
paddings
became
quite
audible,
and
once
or
twice
they
saw
the
sand
scuffed
up,
not
twenty
feet
away,
as
though
by
a
foot
passing
over
it.
Meanwhile
they
were
climbing
a
rise
of
ground,
broken
by
many
small
hummocks
and
dotted
with
thorny
shrubs.
On
the
other
side,
at
the
foot
of
a
long
down-slope,
lay
Ajo.
Once
they
reached
the
summit,
Kendrick
felt
sure
they
could
outdistance
their
pursuers
on
the
descent.
Already,
if
his
watch
was
right,
the
train
was
preparing
to
pull
out.
It
would
be
a
breathless
dash,
but
he
was
confident
they
could
make
it.
So
he
reassured
Marjorie
as
best
he
could,
and
helped
her
on
up
the
slope.
They
were
practically
on
the
summit
and
already
in
view
of
the
little
railroad
station
and
huddle
of
shacks
below--when
suddenly
he
felt
himself
tripped
and
flung
violently
to
the
ground.
At
the
same
instant,
his
companion
emitted
a
scream,
as
she
felt
herself
seized
by
invisible
hands.
