"Maitland seemed to have something on his mind. He came inquiring as to the real cause of his wife's nervousness. Before I had talked to him long I gathered that he had a haunting fear that she did not love him any more, if ever. I fancied that he even doubted her fidelity."
I wondered why the doctor was talking so freely, now, in contrast with his former secretiveness.
"Do you think he was right?" shot out Kennedy quickly, eying Dr. Ross keenly.
"No, emphatically, no; he was not right," replied the doctor, meeting Craig's scrutiny without flinching. "Mrs. Maitland," he went on more slowly as if carefully weighing every word, "belongs to a large and growing class of women in whom, to speak frankly, sex seems to be suppressed. She is a very handsome and attractive woman—you have seen her? Yes? You must have noticed, though, that she is really frigid, cold, intellectual."
The doctor was so sharp and positive about his first statement and so careful in phrasing the second that I, at least, jumped to the conclusion that Maitland might have been right, after all. I imagined that Kennedy, too, had his suspicions of the doctor.
"Have you ever heard of or used cobra venom in any of your medical work?" he asked casually.
Dr. Ross wheeled in his chair, surprised.
"Why, yes," he replied quickly. "You know that it is a test for blood diseases, one of the most recently discovered and used parallel to the old tests. It is known as the Weil cobra-venom test."
"Do you use it often?"
