“I did—more than once; and these two gentlemen, and that lady heard her, too. She said that she meant to kill him all along; and then she said she struck him in the back with a great knife, and he fell forward on his face; and she acted how she struck him, and how he fell.”

“In face of that statement my duty’s plain; the lady must be detained.”

He was going on, but I cut him short.

“Then I say that the lady shall not be detained; I will save you, Mr. Symonds, from making one of the most serious mistakes you ever made in your life. Miss Adair, escort the lady from the room. I will see that no one touches her. Now, constable, out of the way.”

I moved towards the policeman, who did not wait for me to touch him. He slipped aside. The Inspector interposed.

“Now, Mr. Ferguson, I warn you to be careful. May I ask you, Dr. Hume, to explain to this gentleman what are the consequences of impeding the police in the execution of their duty. You might also point out to him how worse than futile such attempts always are.”

Hume was standing near the door. Now he came into the middle of the room. I was surprised by the alteration which had taken place in his appearance since I had observed him last. He seemed to have all at once grown old. Outwardly he was cool and calm; but I, who had some knowledge of the man, perceived that he was making a strenuous effort to retain the mastery of himself in face of some most unusual emotion. He spoke with an exaggeration of his usual deliberative manner.

“You are aware, Mr. Symonds, that I am not a likely person to interfere with the police in the execution of their duty; but it happens, in this case, that I am acquainted with this young lady, and am sure that she has had no more to do with this crime than”—he paused, he drew in his lips, as if to moisten them—“I have. The account which your officer has given you of her behaviour in the adjoining room is very far from being an accurate representation. She is at present suffering from an obscure mental disease. If you were to proceed to arrest her you would run an imminent risk of permanently disturbing the balance of her brain, and of driving her stark mad. The act, and the responsibility for the consequences of the act, would be yours. Let me finish, Inspector. I quite understand that if you were to allow her to pass entirely from your purview you would be assuming a weighty responsibility in a different direction. I am therefore prepared to give you my personal guarantee that she shall remain at your disposal as witness, or in any other capacity, until it has been made plain that she has had no connection whatever with this most unfortunate affair.”

“First of all, what is the lady’s name, who is she, and where does she live?”

“She is Miss Bessie Moore, the well-known actress, and she lives with this other lady, Miss Florence Adair, at 22, Hailsham Road, Brompton.”
