"You have not yet told me," said Rosencrantz, in the assured tones of an inveterate bully, "why you dared to disobey my orders?"

Peggy's thoughts were still with Jimmy. Though she knew nothing of the colossal plot which had just come to light, she trembled to think of what the consequences would be, should the boy be discovered. She answered timidly, in a voice so low as to be hardly audible.

"I have no excuse," she said.

Rosencrantz gave vent to a grunt.

"I should think not," said he, with a quick shrug of the shoulders. "And where's that rascal of a boy?"

Peggy could not answer. For a moment, she thought it was best to tell a deliberate lie, and have done with it; and then, she found she could not. She just stood quite still and silent, unable to lift her eyes from the floor--a very figure of guilt.

Rudolf Stork was a man upon whom little or nothing was lost. He had the eyes of a lynx. He was one whose very liberty, perhaps, depended upon his powers of observation, his memory and his wits. Without a word, he turned upon his heel, in three strides crossed the room, and flung wide open the cupboard door.

And there stood Jimmy Burke, his head half lowered, his face white as a sheet. He took two slow steps forward towards the centre of the room where the three men stood regarding him in amazement, and then stopped dead, apparently afraid to look about him.

Rosencrantz drew in a deep breath, as a man does who is about to take a plunge into ice-cold water. Von Essling let out an oath in his own language, as he drummed with his fingers upon the silver knob of a stout malacca cane. As for Stork, his hand went quickly to his hip-pocket, and a small nickel-plated revolver glittered in the light.

"Eavesdropping!" cried Rosencrantz. "An eavesdropper--by all that's wonderful!"
