They had followed me up Victoria Street, and now, as I stood outside the Duke of Wellington's residence, I could see them moving about on the other side of the way.

What their intentions were I could not say, but that their object was to spy upon my movements, I was quite convinced.

In order to assure myself of this fact I resolved to lay a little trap for them.
Passing down Piccadilly at a sharp pace, I turned into Berkeley Street, some twenty yards or so ahead of them.

Crossing the road I sheltered myself in a doorway and waited.

I had not been there very long, before I observed that they had turned the corner and were coming along in hot pursuit.
