He came rolling down the steps, and the door banged to above him. She heard the key turn and the bolt go home. The rolling steps went past her and down the street to the lilt of a tune. The gentleman who was considering if he would risk his neck was whistling as he went.

“For ye’ll tak the high road,

And I’ll tak the low road,

And I’ll be in Scotland afore ye-”

The words sprang up in Ione’s mind to meet the tune, and with them the impulse to get out of this place into which she had fallen and away from the house where someone whispered, and someone haggled about the price of his neck. It was one of those impulses which take hold of you. She didn’t think about it, she didn’t even know that she was going to obey it. She just found herself running up the area steps and out into the road. It was the sheer blank wall of the fog that stopped her. The moment that she was away from the area and the steps, her sense of direction was gone. She couldn’t see the street-lamp. So far as she was concerned, it was just blotted out. All that remained in the blind world of fog was the failing strains of “ Loch Lomond.” When they were gone she would be all alone.

She began to run, but almost at once she checked herself. If she was to follow him, he mustn’t hear her. She mustn’t run. As long as he went on whistling, she thought she could follow the sound. But she mustn’t let him get far ahead. The fog muffled everything. It would be dreadfully easy to lose the sound, and once it was lost, there would be nothing to guide her.

When she thought about it afterwards she found it extremely difficult to understand why she should have had any desire to follow the rolling Scot. He had certainly had too much to drink, and she had heard him discussing the remuneration he would require for what sounded uncommonly like one of the major crimes. Against this there was nothing reasonable to advance.
