He was at Scotland Yard in his luxurious touring car punctually at the appointed hour. Punctual as he was, though, the inspector was waiting on the step for him.

“Got off all right, inspector,” the barrister remarked as the detective took his seat and the car started. “Only filled up with petrol at a garage after we left my flat, and I told Mrs. Bechcombe that I might be back to lunch. Chauffeur doesn't know where we are going yet. You direct him to the Southampton Road and then I will tell him to put all speed on.”

The day was perfect, no head wind, just a touch of frost in the air. Both men would have enjoyed the long smooth spin if their minds had been free, if their thoughts had not been busy all the time with their journey's end. To the inspector, if all went well, it would spell success, when success had at first seemed hopeless and a long step forward in the great campaign on which he had embarked.

To Steadman it would mean that a certain theory he had held all along was justified.

As they reached Southampton the inspector looked at his watch. “Plenty of time—half an hour to spare!”

They drove straight to the docks and went alongside. The inspector had good reason to expect his prey by the boat train. They had left the car higher up. Steadman waited out of sight. The inspector went on board and ascertained that Mr. Samuel Horsingforth had not so far arrived.

As the boat train drew up, keeping himself well out of sight, Steadman peered forth eagerly. The train was not as crowded as usual, but so far as Steadman could see no Mr. Horsingforth was visible. Then just at the last moment a man of middle height strolled to the gangway—a man, who, though his face and figure were absolutely unknown to the barrister, seemed to have something vaguely, intangibly familiar about him. Steadman was looking out for a slight, spare-looking man, shorter than this one, with the rounded shoulders of a student, pale too, with a short straggling beard and big horn-rimmed glasses. The man at whom he was looking must be at least a couple of inches taller than the one they were in search of, and he was distinctly stout, and his shoulders were square, and he carried himself well. He was clean-shaven too. He had the ruddy complexion of one leading an outdoor life. He smiled as he spoke to a porter about his luggage and Steadman could see his white even teeth and his twinkling grey eyes. Yet, after a momentary pause, the barrister came out into the open and followed up the gangway. Suddenly Steadman saw Inspector Furnival moving forward. The man in front saw too, and came to a sudden stop; stopped and faced round just as he was about to put his foot on deck, and then seeing Steadman stopped again and looked first one way and then the other and finally stepped on deck with an air of jaunty determination.

Inspector Furnival came up to him.

“Samuel Horsingforth, alias John Frederick Hoyle, alias Amos Thompson, I hold a warrant for your arrest on a charge of fraud and embezzlement. It is my duty to warn you that anything you may say will be taken down in writing and may be used in evidence against you.”
