He gave out that he was a Sydney business-man engaged on a motor holiday trip. He said he was an old friend of Mr Jeffrey Stanton, owner of Windee Station, and would visit Mr Stanton before he went on south to Broken Hill. I saw Marks only once-when I went through the hotel after hours to see that only genuine travellers were on the premises. He was thick-set, about five feet ten, brown hair andeyes, aged about fifty. He stayed at Mount Lion two days before driving off to Windee in the morning. It is only eighteen miles, and he arrived there at twelve-fifteen. He lunched with Mr Stanton, and left at half-past two to go to Broken Hill.”

The uniformed man prodded his stick into the ground. “Here is Mount Lion. Here, eighteen miles south-west of thetownship, is Windee homestead. To go to Broken Hill from Windee it is unnecessary to turn back through Mount Lion. The Broken Hill track branches from the Mount Lion track two miles from the homestead, going direct south-east. The junction of the tracks is ten miles from the south boundary, and about the same distance from the east boundary, of Windee.

“Six days after Marks left the homestead his car was found four chains off the road north of the junction. It was in perfect order. There was no sign of Marks. The country all about is a maze of low sand-ridges on which grow pine trees with a sprinkling of mulga.

“I was notified by telephone and went out at once to the abandoned car. Of tracks there were none, for the ground was sandy and dry, and there’d been two windstorms since Marks was last seen. Nevertheless, I organized Mr Stanton’s men on a wide and thorough search, and took two native trackers from a small tribe camped near the homestead in an effort to pick up tracks near the car. The parties were out more than a week. The blacks could pick up no single tracks. In fact they knew, by the nature of the ground, plus the windstorms, that it was a waste of time looking for tracks.”
