The chateau contained a large music room and a miniature theatre in which Mr. Wallingford's musical compositions and operas were performed.

“I have just come from Paris,” said Mr. Wallingford, “where I have made arrangements for six concerts by my orchestra which will play many of my own pieces. Can you not be in Paris in a month and hear them?”

“Tell him your story,” whispered Tom to Quincy, and he did so.

Mr. Wallingford was deeply interested.

“If you find both your father and mother, they deserve another honeymoon. Bring them to Vertano and in the joys of the present we will make them forget the sorrows of the past.”

“I am afraid,” said Quincy, “that such good fortune would be more than miraculous.”

“Come with your mother and friend then,” said Mr. Wallingford as he left them to change cars.

They went to the Hotel Metropole in Vienna. Quincy consulted his guide book.

“Everybody lives in apartment houses in Vienna, so this book says. The question is, in which one shall we find my mother and her maid?”

“All we can do,” said Tom, “is to plug away every day. Keep a-going, keep asking questions, keep our eyes and ears open, and keep up our courage.”
