"Maybe ye had better ask Mr. Davies to let ye out by the back," he said. "If ye call again in half an hour, I may have some news."

"I wonder how Williamson got here?" Andrew said when they reached the street. "There's no train that connects with the North British."

"Came in a car, perhaps," Whitney suggested. "Somehow, I'd like to know. Let's try our garage; everybody puts up there."

They went to the garage and Whitney began to make an unnecessary adjustment to the engine of his side-car.

"I suppose Mr. Williamson comes here when he's in town?" he said to a man at work near by.

"Yes," the man answered. "He's in town the noo."

"Did Mr. Staffer bring him in his car?"

"She's no' in the yard, and Mr. Williamson's for Castle Douglas." The man indicated the motorcycle on which he was working. "I'm tightening her up for the run; no' that she needs it much. Mr. Williamson kens a good machine and always asks for her."

"Is there anything doing at Castle Douglas to-day?"

"No' that I've heard of. He's for the moors, I'm thinking. There's a gun-case to be strapped on the carrier; but if ye're wanting to see him ye must leave word at the office. I'll be away at another job before he comes in."
