Then he looked up with a smile. "Well, I guess you gentlemen are only doing your clear duty after all, and I have no right to stand in the way of it. I'd only ask you not to worry Mrs. Douglas over this matter; for she has enough upon her just now. I may tell you that poor Douglas had just one fault in the world, and that was his jealousy. He was fond of me -- no man could be fonder of a friend. And he was devoted to his wife. He loved me to come here, and was forever sending for me. And yet if his wife and I talked together or there seemed any sympathy between us, a kind of wave of jealousy would pass over him, and he would be off the handle and saying the wildest things in a moment. More than once I've sworn off coming for that reason, and then he would write me such penitent, imploring letters that I just had to. But you can take it from me, gentlemen, if it was my last word, that no man ever had a more loving, faithful wife -- and I can say also no friend could be more loyal than I!"
It was spoken with fervour and feeling, and yet Inspector MacDonald could not dismiss the subject.
"You are aware," said he, "that the dead man's wedding ring has been taken from his finger?"
"So it appears," said Barker.
"What do you mean by 'appears'? You know it as a fact."
The man seemed confused and undecided. "When I said 'appears' I meant that it was conceivable that he had himself taken off the ring."
"The mere fact that the ring should be absent, whoever may have removed it, would suggest to anyone's mind, would it not, that the marriage and the tragedy were connected?"
Barker shrugged his broad shoulders. "I can't profess to say what it means." he answered. "But if you mean to hint that it could reflect in any way upon this lady's honour" -- his eyes blazed for an instant, and then with an evident effort he got a grip upon his own emotions -- "well, you are on the wrong track, that's all."
"I don't know that I've anything else to ask you at present," said MacDonald, coldly.
"There was one small point," remarked Sherlock Holmes. "When you entered the room there was only a candle lighted on the table, was there not?"
"Yes, that was so."
"By its light you saw that some terrible incident had occurred?"
"You at once rang for help?"
"And it arrived very speedily?"
"Within a minute or so."
"And yet when they arrived they found that the candle was out and that the lamp had been lighted. That seems very remarkable."
Again Barker showed some signs of indecision. "I don't see that it was remarkable, Mr. Holmes," he answered after a pause. "The candle threw a very bad light. My first thought was to get a better one. The lamp was on the table; so I lit it."
"And blew out the candle?"
Holmes asked no further question, and Barker, with a deliberate look from one to the other of us, which had, as it seemed to me, something of defiance in it, turned and left the room.
Inspector MacDonald had sent up a note to the effect that he would wait upon Mrs. Douglas in her room; but she had replied that she would meet us in the dining room. She entered now, a tall and beautiful woman of thirty, reserved and self-possessed to a remarkable degree, very different from the tragic and distracted figure I had pictured. It is true that her face was pale and drawn, like that of one who has endured a great shock; but her manner was composed, and the finely moulded hand which she rested upon the edge of the table was as steady as my own. Her sad, appealing eyes travelled from one to the other of us with a curiously inquisitive expression. That questioning gaze transformed itself suddenly into abrupt speech.
"Have you found anything out yet?" she asked.
Was it my imagination that there was an undertone of fear rather than of hope in the question?
"We have taken every possible step, Mrs. Douglas," said the inspector. "You may rest assured that nothing will be neglected."
"Spare no money," she said in a dead, even tone.
