Still it was no good worrying over what couldn’t be helped.  My first job was to get safely into the Walkham woods; after that it would be quite time enough to think about turning burglar.

I sat up and looked out into the mist.  Things were as bad as ever, and quite suddenly it struck me with considerable force that by lying low in this fashion I was making a most unholy idiot of myself.  Here I was growing cold and stiff, and wasting what was probably the best chance I should ever have of reaching Walkhampton.  In fact I was playing right into the hands of the warders.

With an impatient exclamation I jumped to my feet.  The only question was, could I find my way out of the wood, and if I did, how on earth was I to strike the right line over North Hessary?  It was quite on the cards I might wander back into Princetown under the happy impression that I was going in exactly the opposite direction.

For a moment I hesitated; then I made up my mind to risk it.  After all the fog was as bad for the warders as it was for me, and even if I failed to reach the Walkham Valley I should probably find some other equally good shelter before it lifted.  In either case I should have the big advantage of having changed my hiding-place.

Buttoning up my slop, I advanced carefully through the dripping brambles.  One could see rather less than nothing, but so far as I could remember the main Tavistock road was on my right-hand side.  This would leave North Hessary away to the left; so turning in that direction I set my teeth and took my first step forward into the darkness.

I don’t suppose you have ever tried walking through a wood in a fog, but you can take my word for it that a less enjoyable form of exercise doesn’t exist.  I have often wondered since how on earth I managed to escape a sprained ankle or a broken neck, for carefully as I groped my way forward it was quite impossible to avoid all the numerous crevices and overhanging boughs which beset my path.

I must have blundered into about fourteen holes and knocked my head against at least an equal number of branches, before the trees at last began to thin and the darkness lighten sufficiently to let me see where I was placing my feet.  I knew that by this time I must be getting precious near the boundary of the wood, outside which the warders were now doubtless posted at frequent intervals.  So I stopped where I was and sat down quietly on a rock for a few minutes to recover my breath, for I had been pretty badly shaken and winded by my numerous tumbles.

As soon as I felt better I got up again, and taking very particular care where I was treading, advanced on tiptoe with a delicacy that Agag might have envied.  I had taken about a dozen steps when all of a sudden the railings loomed up in front of me through the mist.

I put my hand on the top bar, and then paused for a moment listening breathlessly for any sound of danger.  Except for the faint patter of the rain, however, everything was as silent as the dead.  Very carefully I raised myself on the bottom rail, lifted my legs over, one after the other, and then dropped lightly down on to the grass beyond.
