When Jane started to run down the laboratory passage Jeffrey Ember was superintending the removal of the black silk muffler from Henry’s neck. When they rolled Henry over on to his face he groaned, and when they tied his hands behind his back with the muffler he tried to kick, whereupon Ember produced a piece of rope and they tied his ankles too.

The sound of Jane’s running feet had come very faintly upon Ember’s ear. Henry was groaning and kicking, and Belcovitch was cursing in a steady undertone. It was not until he rose to get the piece of rope that his mind took hold of that faint sound and began to analyse it. There had been a sound in the passage outside—some one moving—some one running. Yes, that was it, some one running, light foot and very fast.

Ember finished tying Henry up and got to his feet.

“There was some one in the passage just now,” he said. “I must go and see. There was something; I heard something. It was like some one running.” He spoke as if to himself, and then turned to Raymond.

“You will stay where you are in that chair—otherwise....” He swung round to Belcovitch.

“If she moves, shoot Captain March at once,” he said, and was gone, leaving the gate ajar behind him.

In the library Jane waited for her call. It came with startling loudness—a bell that seemed to ring inside her head—and then the dreamy voice drawling, “Here y’are.”

In Piggy’s study Isobel Le Mesurier said, “Hullo!”

“Is that Lady Le Mesurier?” said Jane.

“Yes, speaking.”
