Mr. Grooten dropped the cigarette which he had only just lit, and seemed for the moment unconscious of the fact. He made no effort to pick it up. He quivered as though someone had struck him a blow. For a man whose impassivity was almost a part of himself he was evidently deeply agitated.

"The Archduchess—has seen Isobel!" he muttered.

"They met by chance at the Mordaunt Rooms a few afternoons ago," I told him. "The Archduchess was accompanied by a girl of about Isobel's age. We came upon them suddenly, and the likeness was so marvellous that we were all startled. There was something in the nature of a scene. We left the Gallery at once, but the Archduchess sent one of her suite for me. I had some conversation with her concerning Isobel."

"Can you repeat it?" Grooten asked.

"In substance—yes," I told him. "The Archduchess plainly hinted that she believed Isobel to be connected morganatically with her family. She wished to take her under her own charge and provide for her."

"And you?"

"I thought it best to take some time for reflection. I had some idea of looking up the history of the Archduchess's family."

"You made no promise?"

"Certainly not. To tell you the truth, I was influenced by the presence of Lady Delahaye amongst the royal party. I have no faith in Lady Delahaye's good intentions with regard to Isobel."

Mr. Grooten flashed a quick glance upon me.
