altering your hat and necktie. It is usual for a person addressing
another to take note of his necktie, and probably of his hat, if of
nothing else, and thus it is often useful to carry a necktie and a
cap of totally different hue from that which you are wearing, ready to
change immediately in order to escape recognition a few minutes later.

disguise himself at very short notice when he observed that he was
recognised on a railway station. The first sketch shows him as he
entered a waiting-room shortly after his suspicions were aroused.

simple though it may seem, was entirely successful._]

I learnt this incidentally through being interviewed some years ago at
a railway station. A few minutes after the ordeal I found myself close
up to my interviewer, when he was re-telling the incident to a brother
journalist, who was also eager to find me. "He is down there, in one
of the last carriages of the train. You will know him at once; he is
wearing a green Homburg hat and a red tie, and a black coat."

Fortunately I had a grey overcoat on my arm, in which was a travelling
cap and a comforter. Diving into the waiting-room, I effected a "quick
change" into these, crammed my hat into my pocket, and tottered back,
with an invalid shuffle, to my carriage. I re-entered it under the
nose of the waiting reporter without being suspected, and presently
had the pleasure of being carried away before him unassailed.

On a recent occasion in my knowledge a man was hunted down into a back
street which was a _cul-de-sac_, with no exit from it. He turned into
the door of a warehouse and went up some flights of stairs, hoping to
find a refuge, but, finding none, he turned back and came down again
and faced the crowd which was waiting outside, uncertain which house
he had entered.

By assuming extreme lameness in one leg, hunching up one shoulder,
and jamming his hat down over a distorted-looking face, he was able
to limp boldly down among them without one of them suspecting his
individuality.

In regard to disguises, hair on the face--such as moustache or
beard--are very usually resorted to for altering a man's appearance
but these are perfectly useless in the eye of a trained detective
unless the eyebrows also are changed in some way.
