“They said he was a commercial traveller.” It was curious that there was no mention of this Georsh as an occupant of the house; he was not on the list given to Wenk. Wenk went to the Town Register Office, and with the help of the officials he ascertained that one occupant of the house had been a George Hinrichsen from the Elbe district. He had left the place about a month before, and said he was going to Ravensburg, and after that the room had been taken by a commercial traveller named Poldringer. It was quite clear to Wenk that Hinrichsen and Poldringer the traveller were one and the same person. It was just a month ago that Hull had had that memorable conversation with Wenk. And Hinrichsen and Poldringer were the same individual as the murderer of Hull, or at least the person who directed the murder, and it was his name that the dancer had called out. Possibly the direction Hinrichsen had taken in departure also agreed with this, for Constance lay near Ravensburg, and Switzerland could be reached from there. Wenk telegraphed to the Constance head-office, with special reference to the passport stations. A few hours later the police officials there telegraphed back that a man named Poldringer had notified his arrival there. He gave Bavaria as his native State, and this had struck the registering official as curious, because the man used a dialect that was unmistakably North German. On that account the police kept him under surveillance. They ascertained that he frequented the society of people who were suspected of smuggling goods across the Swiss frontier. He often travelled by the steamer to Lindau. “Expect me to-day in Constance,” telephoned Wenk finally. Wenk immediately prepared for a journey. He could reach Constance before night if the little monoplane belonging to a friend of his, which was always at his service, were ready for a flight. He telephoned to him and ascertained that it was. At four o’clock he departed, and in the deepening twilight he descended at the Petershaus aerodrome near Constance. The police described the locality in which these profiteers and smugglers were to be found. He disguised himself as a chauffeur and went to one of their inns to get some supper. He addressed one man whom he thought to be of their party, saying that he could get hold of two cars, and also some sort of export licence, as long as it wasn’t looked at too closely, but if he had the help of one or, better still, of two bold fellows it could be done quite easily. There would be a profit of about ten thousand in it, for the cars were bought in the autumn of 1918 and had been kept hidden ever since. They were first-class cars that had belonged to two generals. The other did not take long to consider. He would broach the matter to a friend of his, and the three of them would soon pull it off. They went together later to another tavern, which the friend often frequented, but he did not appear.
