“How do you know that much violence has been used?—though there are women who are capable of as much violence as men. But, in this case, so far, there is nothing to show that much strength has been exerted. It is a question of what instrument has been employed. Obviously it is one of a most extraordinary and most deadly kind, and one which I should imagine would be as likely to be found in a woman’s possession as a man’s; indeed, I should say more likely, because I should expect to find a man preferring to trust to his own right hand. Let me tell you this, Ferguson. You are making a serious mistake in endeavouring to associate Philip Lawrence with this matter. I know him well. He is a man of high position and noble character; as incapable of such a deed as you. Indeed, I know him well enough to be aware that he is incapable; I have not sufficient knowledge of you to say, with certainty, of what you may be capable.”

“Your language is quite unwarranted. I have made no endeavour of the kind.”

“Are you perfectly candid? Are you sure that there is nothing at the back of your mind? My position here is quasi-official. It is my duty to ascertain how this man came to his death. Yet, while you refuse to answer my inquiries, questioning my right to make them, you volunteer some tittle-tattle about Philip Lawrence, and produce, with something very like a flourish of triumph, a collar with his name on, which, you say, you found upon the floor. I warn you again that, if you attempt to drag in Philip Lawrence’s name, you will be guilty of a serious injustice, the consequences of which will inevitably recoil on your own head.”

“Listen to me, Hume, in your turn. In the first place, I don’t understand why you show me such an aggressive front. And, anyhow, you exaggerate the importance of your position. You merely happen to be the first doctor of whom I could think. Your business is to make a medical examination; so far, in that direction, I cannot say that I have seen you make any undue exertions. To suggest that your office is, in any sense, judicial, is sheer absurdity. We will stop at that. Some men would have regarded the questions which you have put to me as intentionally impertinent. I have enough acquaintance with you to know that it is your unfortunate manner which is to blame, and that your intention was innocuous.

“But let me add this: I know nothing of Mr. Philip Lawrence; I have never seen the man in my life. But, since he was seen to leave the building at an early hour this morning, in a somewhat curious fashion, exhibiting all the marks of haste; and since his brother has now been found here lying dead, I think, in spite of your ardent championship, he will be called upon to give some sort of explanation.”

Why Hume behaved as he immediately did is beyond my comprehension. He came close up to me, looking me full in the face, in distinctly unfriendly fashion.

“Then I say you lie.”

He said it quietly—it is not his custom to speak loudly—but he said it with unmistakable decision. While I was wondering whether or not I should knock the fellow down, Atkins came in with a policeman at his heels. It was time.

CHAPTER V.
A CURIOUS CASE

I had only just returned to my own rooms when Mrs. Peddar appeared.
