no mercy.

I looked back, but there was nothing in the landscape. The sun
glinted on the metals of the line and the wet stones in the stream,
and you could not have found a more peaceful sight in the world.
Nevertheless I started to run. Crouching low in the runnels of the
bog, I ran till the sweat blinded my eyes. The mood did not leave
me till I had reached the rim of mountain and flung myself panting
on a ridge high above the young waters of the brown river.

From my vantage-ground I could scan the whole moor right
away to the railway line and to the south of it where green fields
took the place of heather. I have eyes like a hawk, but I could see
nothing moving in the whole countryside. Then I looked east
beyond the ridge and saw a new kind of landscape--shallow green
valleys with plentiful fir plantations and the faint lines of dust
which spoke of highroads. Last of all I looked into the blue May
sky, and there I saw that which set my pulses racing ...

Low down in the south a monoplane was climbing into the
heavens. I was as certain as if I had been told that that aeroplane
was looking for me, and that it did not belong to the police. For an
hour or two I watched it from a pit of heather. It flew low along
the hill-tops, and then in narrow circles over the valley up which I
had come' Then it seemed to change its mind, rose to a great
height, and flew away back to the south.

I did not like this espionage from the air, and I began to think
less well of the countryside I had chosen for a refuge. These
heather hills were no sort of cover if my enemies were in the sky,
