At ten minutes past ten he was in the street, on his way to the nearest cab-stand, and I and my subordinates were close on his heels.

I had not overheard them appoint a place of meeting when following them in the Park on the previous day, but I soon found that we were proceeding in the old direction of the Avenue Road gate.

We stopped outside, to avoid exciting suspicion.

I got out to follow the cab on foot.
