"Were you speaking to me?"

Mr. Paxton's fingers itched to knock the smoker down. But situated as he was, a row in public just then would have been sheer madness. He adopted what was probably an even more effective plan. He signalled to a passing official.

"Guard!" The man approached. "This person has been following me from my hotel. Be so good as to call a constable. His proceedings require explanation."

The man began to bluster.

"What do you mean by saying I've been following you? Who are you, I should like to know? Can't any one move about except yourself? Following you, indeed! It's more likely that you've been following me!"

A constable came up. Mr. Paxton addressed him in his cool, incisive tones.

"Officer, this person has followed me from my hotel to the station; from the station to the booking-office; from the booking-office to the bookstall; and now he is following me from the bookstall to the train. I have some valuable property on me, with which fact he is possibly acquainted. Since he is a complete stranger to me, I should be obliged if you would ask him what is the cause of the unusual interest which he appears to take in my movements."

The man with the cigar became apologetic.

"The gentleman's quite mistaken; I'm not following him; I wouldn't do such a thing! I'm going to town by this train, and it seems that this gentleman's going too, and perhaps that's what's made him think that I was following. If there's any offence, I'm sure that I beg pardon."

The man held out his hand--it was unclean and it was big--as if expecting Mr. Paxton to grasp it. Mr. Paxton, however, moved away addressing a final observation to the constable as he went.
