"Yes, we have been married five years."
"Have you heard him speak of anything which occurred in America and might bring some danger upon him?"
Mrs. Douglas thought earnestly before she answered. "Yes," she said at last, "I have always felt that there was a danger hanging over him. He refused to discuss it with me. It was not from want of confidence in me--there was the most complete love and confidence between us--but it was out of his desire to keep all alarm away from me. He thought I should brood over it if I knew all, and so he was silent."
"How did you know it, then?"
Mrs. Douglas's face lit with a quick smile. "Can a husband ever carry about a secret all his life and a woman who loves him have no suspicion of it? I knew it by his refusal to talk about some episodes in his American life. I knew it by certain precautions he took. I knew it by certain words he let fall. I knew it by the way he looked at unexpected strangers. I was perfectly certain that he had some powerful enemies, that he believed they were on his track, and that he was always on his guard against them. I was so sure of it that for years I have been terrified if ever he came home later than was expected."
"Might I ask," asked Holmes, "what the words were which attracted your attention?"
"The Valley of Fear," the lady answered. "That was an expression he has used when I questioned him. 'I have been in the Valley of Fear. I am not out of it yet.'--'Are we never to get out of the Valley of Fear?' I have asked him when I have seen him more serious than usual. 'Sometimes I think that we never shall,' he has answered."
"Surely you asked him what he meant by the Valley of Fear?"
