"You—you only want to go in the passage," she said.

"That'll do us, mum," said the foreman. "You stay up 'ere, Bill," he added, turning to the man he had instructed to go for the police.

Mrs. Naylor led the way to the lower regions, unconscious that not three but seven men were following her, the last four with rubber-soled boots.

She had scarcely taken a step along the passage at the foot of the basement stairs, when her arms were gripped from behind and a pad held over her mouth. She struggled against the sweet-smelling sickly fumes; then the relaxing of her limbs told that she had temporarily left for realms where Mr. Naylor was not.

The basement was composed of a kitchen, immediately on the right of the stairs, and a breakfast-room, the entrance to which lay a few paces along the passage. At the end of the passage was a door leading into the area.

Without a sound the men divided themselves, one went to the area door, two remained by the kitchen door, where Susan could be heard clattering crockery, whilst the other four stood outside the door leading to the breakfast-room. One of them gently turned the handle; it was locked. He made a signal to the two men at the kitchen door. One quietly entered.

A moment later Susan looked up with a start to find herself gazing down the barrel of an automatic pistol, whilst before her eyes was presented a card on which was printed, "Come and make the signal to get the door of the breakfast-room open, otherwise you will be shot."

For a fraction of a second she hesitated, then a strange light flashed into her eyes, suggestive half of cunning, half of relief, and with an understanding nod she walked to the breakfast-room door. One of the men placed her in such a position that she would not be in the way of the entrance of the others when the door was opened.

Very deliberately she knocked and paused—knock—knock—knock, pause, knock—knock.

They waited breathlessly. The sound of a key being cautiously turned was presently heard. A moment after a line of white appeared beside the green paint of the door, as it was slowly and cautiously opened.
