“Exactly. She does not shine as a wife even in her own account of what occurred. I am not a whole-souled admirer of womankind, as you are aware, Watson, but my experience of life has taught me that there are few wives, having any regard for their husbands, who would let any man’s spoken word stand between them and that husband’s dead body. Should I ever marry, Watson, I should hope to inspire my wife with some feeling which would prevent her from being walked off by a housekeeper when my corpse was lying within a few yards of her. It was badly stage-managed; for even the rawest investigators must be struck by the absence of the usual feminine ululation. If there had been nothing else, this incident alone would have suggested a prearranged conspiracy to my mind.”
“You think then, definitely, that Barker and Mrs. Douglas are guilty of the murder?”
“There is an appalling directness about your questions, Watson,” said Holmes, shaking his pipe at me. “They come at me like bullets. If you put it that Mrs. Douglas and Barker know the truth about the murder, and are conspiring to conceal it, then I can give you a whole-souled answer. I am sure they do. But your more deadly proposition is not so clear. Let us for a moment consider the difficulties which stand in the way.
“We will suppose that this couple are united by the bonds of a guilty love, and that they have determined to get rid of the man who stands between them. It is a large supposition; for discreet inquiry among servants and others has failed to corroborate it in any way. On the contrary, there is a good deal of evidence that the Douglases were very attached to each other.”
