Her eyes suddenly glowed with a new light.

“I will not be trifled with,” she insisted. “If you wish to succeed in whatever scheme you have on hand, you must not make an enemy of me. I shall expect you at seven o'clock.”

She passed away from him into the restaurant. Mr. Mangan, now freed from his friends, rejoined his host, and the two men took their places at the side table to which they were ushered with many signs of attention.

“Wasn't that the Princess Eiderstrom with whom you were talking?” the solicitor asked curiously.

“A lady addressed me by mistake,” Dominey explained. “She mistook me, curiously enough, for a man who used to be called my double at Oxford. Sigismund Devinter he was then, although I think he came into a title later on.”

“The Princess is quite a famous personage,” Mr. Mangan remarked, “one of the richest widows in Europe. Her husband was killed in a duel some six or seven years ago.”

Dominey ordered the luncheon with care, slipping into a word or two of German once to assist the waiter, who spoke English with difficulty. His companion smiled.

“I see that you have not forgotten your languages out there in the wilds.”

“I had no chance to,” Dominey answered. “I spent five years on the borders of German East Africa, and I traded with some of the fellows there regularly.”
