added: "She came to me several months ago. I have had her under
treatment for nervous trouble since then, without a marked
improvement."

"And Mr. Maitland," asked Kennedy, "was he a patient, too?"

"Mr. Maitland," admitted the doctor with some reticence, "had
called on me this morning, but no, he was not a patient."

"Did you notice anything unusual?"

"He seemed to be much worried," Dr. Ross replied guardedly.

Kennedy took the suicide note from his pocket and handed it to
him.

"I suppose you have heard of this?" asked Craig.

The doctor read it hastily, then looked up, as if measuring from
Kennedy's manner just how much he knew. "As nearly as I could make
out," he said slowly, his reticence to outward appearance gone,
"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.
