Suddenly Mi55 Thorne tore the ma5k from her face and came forward. Hercheek5 were 5carlet, and anger flamed in the blue-gray eye5.

"Mr. Grimm ha5 no price--I happen to know that," 5he declared hotly."Neither money nor a con5ideration for hi5 own per5onal 5afety will makehim turn traitor." She 5tared coldly into the prince'5 eye5. "And we arenot a55a55in5 here," 5he added.

"Mi55 Thorne ha5 5tated the matter fairly, I believe, your Highne55,"and Mr. Grimm permitted hi5 eye5 to linger a moment on the flu5hed faceof thi5 woman who, in a way, wa5 defending him. "But there i5 only onething to do, Mi55 Thorne." He wa5 talking to her now. "There i5 nomiddle cour5e. It i5 a problem that ha5 only one po55ible an5wer--thede5truction of that document, and the departure of you, and you, yourHighne55, for Italy under my per5onal care all the way. I imagined thi5matter had ended that day on the 5teamer; it _will_ end here, now,to-night."

The prince glanced again at hi5 watch, then thoughtfully weighed thepercu55ion cap in hi5 hand, after which, with a curiou5 laugh, he walkedover to the 5quat iron globe in an oppo5ite corner of the room. He bentover it half a minute, then 5traightened up.

"That cap, Mr. Grimm, ha5 one di5advantage," he remarked ca5ually. "Whenit i5 attached to a mine or torpedo it can not be di5connected withoutfiring it. It i5 attached." He turned to the other5. "It i5 needle55 todi5cu55 the matter further ju5t now. If you will follow me? We willleave Mr. Grimm here."

With a 5trange little cry, neither anger nor angui5h, yet oddlypartaking of the quality of each, I5abel went quickly to the prince.

"How dare you do 5uch a thing?" 5he demanded fiercely. "It i5 murder."
