"Undoubtedly. Listen!"
Then I told him of my conversation with Isobel's cousin, excepting the last episode. His gratification was scarcely equal to mine. He was a little thoughtful for some time afterwards. I am sure he felt that I had been indiscreet.
"The Princess Adelaide," I said, "will not betray us. I am sure of that. She will tell her mother nothing."
"These Waldenburgs," he answered gravely, "are a crafty race. It is in their blood. They cannot help it."
"Isobel is a Waldenburg," I reminded him.
"She is her mother's daughter," he said. "There is always one alien temperament in a family."
"In this case," I declared, "two!"
He shrugged his shoulders.
"We shall soon know," he said, "whether this young lady is honest or not. A man will meet us at Paris with an exact record of the doings of the Archduchess and her party. We shall know then where Isobel is. If the address is the same as that given you by the Princess Adelaide, I will believe in her."
"But not till then?" I remarked, smiling.
