apart,
and getting a little finer article with each change, until I should
finally reach silk and velvet, and be ready for my project. So
I started.

But the scheme fell through like scat! The first corner I turned,
I came plump upon one of our slaves, snooping around with a watchman.
I coughed at the moment, and he gave me a sudden look that bit right
into my marrow. I judge he thought he had heard that cough before.
I turned immediately into a shop and worked along down the counter,
pricing things and watching out of the corner of my eye. Those
people had stopped, and were talking together and looking in at
the door. I made up my mind to get out the back way, if there
was a back way, and I asked the shopwoman if I could step out
there and look for the escaped slave, who was believed to be in
hiding back there somewhere, and said I was an officer in disguise,
and my pard was yonder at the door with one of the murderers in
charge, and would she be good enough to step there and tell him
he needn't wait, but had better go at once to the further end of
the back alley and be ready to head him off when I rousted him out.

She was blazing with eagerness to see one of those already celebrated
murderers, and she started on the errand at once. I slipped out
the back way, locked the door behind me, put the key in my pocket
and started off, chuckling to myself and comfortable.

Well, I had gone and spoiled it again, made another mistake.
A double one, in fact. There were plenty of ways to get rid of
that officer by some simple and plausible device, but no, I must
pick out a picturesque one; it is the crying defect of my character.
And then, I had ordered my procedure upon what the officer, being
human, would _naturally_ do; whereas when you are least expecting it,
a man will now and then go and do the very thing which it's _not_
natural for him to do. The natural thing for the officer to do,
in this case, was to follow straight on my heels; he would find
a stout oaken door, securely locked, between him and me; before
he could break it down, I should be far away and engaged in slipping
into a succession of baffling disguises which would soon get me
into a sort of raiment which was a surer protection from meddling
law-dogs in Britain than any amount of mere innocence and purity
of character. But instead of doing the natural thing, the officer
took me at my word, and followed my instructions. And so, as I
came trotting
