She shook hands with Cardo, and placed a chair for him at the well-filled table. He took his seat with a pleasant smile, but soon fell into his usual dreamy state, which the company at a sign from Dr. Belton took no notice of. "I do believe, Williams," said Dr. Belton at last, "that I have never introduced you to my friends. These are Mr. and Mrs. Wynne." Cardo looked up almost eagerly. "Cardo Wynne?" he said. "No," said the doctor; "Mr. Lewis Wynne. But do you know that name?" "Yes, Cardo Wynne." "Is that your name?" asked the shrewd doctor. "Yes, Cardo Wynne." "Merciful goodness!" said the host, in excited astonishment, which his wife seemed in a great measure to share, "that is the name of my brother's son, Caradoc, commonly called Cardo Wynne; that is what Dr. Hughes told us, Nellie, didn't he?" "Yes, I have often thought of the name and wondered what he was like. How sad," she said, "and such a handsome fellow, too." "Caradoc!" Dr. Belton called suddenly. "Yes," said Cardo, with one of his pleasant smiles, "Cardo Wynne, Brynderyn." "Good heavens!" said Mr. Wynne, "there can be no doubt about it; that is my brother's home." And both he and Dr. Belton, aided by Mrs. Wynne's gentle suggestions, made every endeavour to elicit further information from Cardo, but in vain. He had fallen again into an apparently unconscious and deadened stupor. "Sunstroke, did you say? are you sure of that, Belton?" "Not at all," said the doctor; "in fact, I have had serious doubts of it lately, and to-day's experience decides me. I will have a thorough examination of his skull." "I will ride in to-morrow, to hear what further discoveries you have made," said Mr. Wynne. And Dr. Belton returned home early, leaving his host and hostess deeply interested. Calling Sister Vera to him he told her of his plans. "I have long thought it possible that poor fellow might have had a blow of some kind on his head, and that he is still suffering from the effects of it. I shall at once administer an anaesthetic and have a thorough examination of his head. The idea of sunstroke was so confirmed by the symptoms when he was brought to the hospital that no one thought of anything else." "How soon?" asked the nurse. "To-morrow--three o'clock." And the next afternoon, Cardo's head was thoroughly examined, with the result that Dr. Belton soon found at the back of the skull near the top a small but undoubted indentation. "Of course," he said, "we must have been blind not to guess it before; but we are blind sometimes--very blind and very stupid." Cardo was kept under the influence of a sedative that night, and next day Dr. Belton, with the promptness of action which he now regretted he had not sooner exercised, procured the help of one of the most noted specialists in Sydney, and an operation was successfully performed.
