The District Attorney said, “Well, who did you see? Who did you see?”
Nugent was very still and very observant-as, I suddenly realized, everyone in the room was watching, too, and listening. There was indeed a strained and queer silence. I said slowly, confused not so much by the silence as by the singularly intent quality in it, “I didn’t see anyone. I don’t know who it was. I saw nothing.”
“But you…” began Soper explosively, and Nugent said, “All right, Miss Keate. We believe you.” His eyes looked very narrow and green. He went on quickly, “You were in the library when you heard the sound of something falling. What did you do?”
“I ran upstairs.” I told him of it again, briefly. And brought forward what seemed to be, up to then, a bit of new evidence, or at least a new fact. That was the matter of Craig’s being found in the linen closet, unconscious and bleeding from a bruise on his temple.
“He says somebody was in the hall and struck him,” I explained.
The District Attorney interrupted. “Who?”
“He said he doesn’t know. But if someone did that it proves there was an intruder, a-a thief…”
“But he said he was in the hall when he was struck,” said Soper, looking a little impressed with his own astuteness, and very pompous. “You say you found him in the linen room.”
“I did. Or rather Miss Cable found him there first.” Again glances went to Drue; again no one questioned her. “Someone must have dragged him into the linen closet and left him there. A man, I mean.”
“A woman could have done it,” began Soper, and Nugent cut in rather quickly. “I’ll question Craig Brent later,” he said, his eyes still very green and thoughtful, however. Soper, brought up short, frowned, tapped his stomach and began again briskly. “Now then, about Conrad Brent’s business affairs…”
That did not take a very long time; everyone I think was convinced that Conrad’s business affairs were in good order and in any case it would be an easy matter for them to find out through his bankers and his lawyer. There seemed to be, however, little question on that point. He had been a rich man, living well within an income which was, certainly, on the more or less lavish side. Only later inquiry could confirm it, but just then there seemed to be no reasonable doubt but that his affairs were perfectly balanced and sound.
Nothing however was said of his will-which seemed to me another omission. After that they went into the matter of alibis-very cautiously, very suavely, so one didn’t at first realize the exact trend of all their detailed questions of time. In the end, however, so far as I could see, no one really had an alibi except Craig. Nicky, at least, had admitted his presence in the morning room when Conrad returned. Had he seen Drue? Was he going to tell of her interview with Conrad? There was no way to know and no way to read Nicky’s enigmatic face. At length the District Attorney observed, rather pettishly, that there was no alibi, really, for murder by poison, looked impatiently at Nugent and fidgeted. Nugent looked back at him and shook his head, only a little, almost imperceptibly, but as if he’d said, “Wait-not yet.”
I saw that. And I thought I prepared myself for it. I didn’t really; no one does against catastrophe. But I knew that it was coming; they had asked about a hypodermic, so they had seen that tiny red mark on Conrad Brent’s arm. They had searched Drue’s room and mine and had taken away the little bag in which she carried instruments and the few drugs she had, so they knew she had a supply of digitalis and knew she didn’t have a hypodermic-as I had and as any nurse normally would have. They had established the fact that Conrad’s medicine was gone, box and all, so he couldn’t have taken it himself. They wouldn’t have far to look for a motive, or a witness of sorts, either, for Nicky must have seen Drue going to the library even if, for any purpose of his own, he did not then admit it. Above all, the look Soper and Nugent exchanged admitted a previously agreed-upon purpose.
So they had not yet questioned Drue. My feeling about that was right. Obviously they thought that it would weaken her to have to sit there before them and hear the case built up-possibilities eliminated, circumstances set forth so they were indisputable.
I felt cold and queerly stiff, as if all my muscles had tightened hard. I felt that I had to look at Drue and I wouldn’t.
It came sooner than I expected and it was worse. Maud at last brought the thing to its ugly climax. She said, suddenly and impatiently, interrupting a question as to any possibility of the medicine box having been empty and thrown away by Conrad himself, previous to his attack, “Nonsense!”
Everyone looked at her. She said again, “That’s utter nonsense! Conrad never would have done that. He always kept a supply of digitalis on hand. Besides, as Claud has already told you, his prescription had been refilled only three days ago. He hadn’t had an attack since, so it was a full, new supply. And I don’t see why you don’t get to the point. He was given a hypodermic, you know that; Claud saw what he felt sure was the mark and told me. Nobody but a nurse would have given him a hypodermic-a nurse or a doctor, and Claud wasn’t here. And you know who had a motive.”
I said quickly, “A hypodermic mark?”
Nugent glanced at me and Maud stopped, shooting a light black look at me. Nugent said, “Do you want to say something, Nurse Keate?”
“Yes. I don’t see how anyone, even a doctor, can make a positive statement about the mark made by a hypodermic needle. It is very small; frequently so small that it can’t be seen at all. The skin is elastic and instantly closes after the needle is withdrawn.”
Maud’s eyes snapped. “It frequently shows, too.”
I shrugged. “I don’t question Dr. Chivery’s statement to the effect that he found some sort of small mark that might have been made by a hypodermic needle. I do question anyone being able to say with any degree of certainty that a-well, a bare pinprick is the mark of a needle.”
“Miss Keate,” said Maud. “You are not here to question the veracity of the doctor you are working for!”
“It’s the plain truth,” I said. “Ask anyone.”
Maud whirled around toward Nugent. “Dr. Chivery’s word has never been questioned. As I was about to say, it is obvious that only one person in the house had a motive. That was Drue Cable.”
“Mrs. Chivery…” began Nugent, but she went on so vehemently that her tight little body jerked; her black eyes plunged in little bursts from one to the other of us.
“She must have come down to the library to see him; to try to persuade him not to make her go. He had told her she must leave today. She threatened him, yesterday afternoon. I heard her and so did you, Nicky. You heard her say, ‘I could kill you for this.’ I know exactly what happened. She came to the library and she accused him of breaking up her marriage. Conrad had an attack and asked her for medicine; she went to the desk and-and took the medicine away, pretended it was gone. So Conrad, dying, begged her to help him. She was a nurse. How could he know what she would do…?”
“Stop! We’ll get a lawyer. You can’t accuse…” I rose and Nugent was at my side, his hand tight on my arm. Drue looked like a ghost, white, rigid, with great dark eyes fastened on Maud. There was a shadow of a smile on Alexia’s lips. Maud swept on vigorously, black eyes snapping. “So she gave him a hypodermic of digitalis and she gave him too much. It killed him. As she planned. She thought it would never be traced. That’s how it happened…”
