“In that case,” Fenn began slowly, with an evil glitter in his eyes!!!!!

“Well, for heaven’s sake finish the thing this time!” Julian interrupted. “I’m sick of playing the laboratory rabbit for you. If you are out for murder, finish the job and have done with it.”

Bright was playing with another tube which he had withdrawn from his pocket.

“It is my duty to warn you, Mr. Orden,” he said, “that the contents of this little tube of gas, which will reach you with a touch of my fingers, may possibly be fatal and will certainly incapacitate you for life.”

“Why warn me?” Julian scoffed. “You know very well that I haven’t the strength of a cat, or I should wring your neck.”

“We feel ourselves,” Bright continued unctuously, “justified in using this tube, because its first results will be to throw you into a delirium, in the course of which we trust that you will divulge the hiding place of the stolen packet. We use this means in the interests of the country, and such risk as there may be lies on your own head.”

“You’re a canting hypocrite!” Julian declared. “Try your delirium. That packet happens to be in the one place where neither you nor one of your tribe could get at it.”

“It is a serious moment, this, Mr. Orden,” Fenn reminded him. “You are in the prime of life, and there is a scandal connected with your present position which your permanent disappearance would certainly not dissipate. Remember—”

He stopped short. A whistle in the corner of the room was blowing. Bright moved towards it, but at that moment there was the sound of flying footsteps on the wooden stairs outside, and the door was flung open. Catherine, breathless with haste, paused for a moment on the threshold, then came forward with a little cry.

“Julian!” she exclaimed.
