"Septimus Thirsk." He announced himself with a remnant of military precision, as if an old memory had unaccountably slipped through and prompted him. "What can I do for you, sir?" He ignored his brother-in-law, in whose house he apparently lived, and Cyprian, who had retreated to the window embrasure.

“Were you at home on Monday, the day before Mrs. Haslett was killed, sir?" Monk asked politely.

"I was out, sir, in the morning and for luncheon," Septimus answered, still standing almost to attention. "I spent the afternoon here, in my quarters most of the time. Dined out." A shadow of concern crossed his face. "Why does that interest you, sir? I neither saw nor heard any intruder, or I should have reported it."

"Mrs. Haslett was killed by someone already in the house, Uncle Septimus," Cyprian explained. "We thought Tavie might have said something to you which would give us some idea why. We're asking everyone."

"Said something?" Septimus blinked.

Basil's face darkened with irritation. "For heaven's sake, man, the question is simple enough! Did Octavia say or do anything that led you to suppose she had stumbled on a secret unpleasant enough to cause someone to fear her! It's hardly likely, but it is necessary to ask!"

"Yes she did!" Septimus said instantly, two spots of color burning on his pale cheeks. "When she came in in the late afternoon she said a whole world had been opened up to her

and it was quite hideous. She said she had one more thing to discover to prove it finally. I asked her what it was, but she refused to say."

Basil was stunned and Cyprian stood paralyzed on the spot.

"Where had she been, Mr. Thirsk?" Monk asked quietly. "You said she was coming in."

"I have no idea," Septimus replied with the grief replacing anger in his eyes. "I asked her, but she would not tell me, except that one day I would understand, better than anyone else. That was all she would say."

"Ask the coachman," Cyprian said immediately. "He'll know."

"She didn't go in our coaches." Septimus caught Basil's eye. "I mean your coaches," he corrected pointedly. "She walked in. I presume she either walked all the way or found a hansom."

Cyprian swore under his breath. Basil looked confused, and yet his shoulders eased under the black cloth of his jacket and he stared beyond them all out of the window. He spoke with his back to Monk.

“It seems, Inspector, as if the poor girl did hear something that day. It will be your task to discover what it was-and if you cannot do that, to deduce in some other way who it was who killed her. It is possible we may never discover why, and it hardly matters." He hesitated, for a moment more absorbed in his own thoughts. No one intruded.

"If there is any further help the family can give you, we shall of course do so," he continued. "Now it is past midday and I can think of no purpose in which we can assist you at present. Either you or your juniors are free to question the servants at any time you wish, without disturbing the family. I shall instruct Phillips to that effect. Thank you for your courtesy so far. I trust it will continue. You may report any progress you make to me, orifl am not present, to my son. I would prefer you did not distress Lady Moidore."

"Yes, Sir Basil." He turned to Cyprian. "Thank you for your assistance, Mr. Moidore." Monk excused himself, and was shown out, not by the butler this time but by a very striking footman with bold eyes and a race whose handsomeness was spoiled only by a small, clever mouth.

In the hallway he saw Lady Moidore and had every intention of passing her with no more than a polite acknowledgment, but she came towards him, dismissing the footman with a wave of her hand, and he had no option but to stop and speak with her.

"Good day, Lady Moidore."

It was hard to tell how much the pallor of her face was natural, an accompaniment to her remarkable hair, but the wide eyes and the nervous movements were unmistakable.

"Good morning, Mr. Monk. My sister-in-law tells me you believe there was no intruder in the house. Is that so?"

He could save her nothing by lying. The news would be no easier coming from someone else, and the mere fact that he had lied would make it impossible for her to believe him in future. It would add another confusion to those already inevitable.

"Yes ma'am. I am sorry."

She stood motionless. He could not even see the slight motion of her breathing.

"Then it was one of us who killed Tavie," she said. She surprised him by not flinching from it or dressing it in evasive words. She was the only one in the family to make no pretense that it must have been one of the servants, and he admired her intensely for the courage that must have cost.

"Did you see Mrs. Haslett after she came in that afternoon, ma'am?" he asked more gently.

"Yes. Why?"

"It seems she learned something while she was out which distressed her, and according to Mr. Thirsk, she intended to pursue it and discover a final proof of the matter. Did she confide anything of it to you?"

"No." Her eyes were so wide she seemed to stare at something so close to her she could not blink. "No. She was very quiet during dinner, and there was some slight unpleasantness with-" She frowned. "With both Cyprian and her father. But I assumed she had one of her headaches again. People are occasionally unpleasant with each other, especially when they live in the same house day in and day out. She did come and say good-night to me immediately before she went to bed. Her dressing robe was torn. I offered to mend it for her-she was never very good with a needle-" Her voice broke for just a moment. Memory must have been unbearably sharp, and so

very close. Her child was dead. The loss was not yet wholly grasped. Life had only just slipped into the past.

He hated having to press her, but he had to know.

“What did she say to you, ma'am? Even a word may help."

"Nothing but 'good night,' " she said quietly. "She was very gentle, I remember that, very gentle indeed, and she kissed me. It was almost as if she knew we should not meet again." She put her hands up to her face, pushing the long, slender fingers till they held the skin tight across her cheekbones. He had the powerful impression it was not grief which shook her most but the realization that it was someone in her own family who had committed murder.

She was a remarkable woman, possessed of an honesty which he greatly respected. It cut his emotion, and his pride, that he was socially so inferior he could offer her no comfort at all, only a stiff courtesy that was devoid of any individual expression.

"You have my deep sympathy, ma'am," he said awkwardly. "I wish it were not necessary to pursue it-" He did not add the rest. She understood without tedious explanation.

She withdrew her hands.

"Of course," she said almost under her breath.

"Good day, ma'am."

"Good day, Mr. Monk. Percival, please see Mr. Monk to the door."

The footman reappeared, and to Monk's surprise he was shown out of the front door and down the steps into Queen Anne Street, feeling a mixture of pity, intellectual stimulation, and growing involvement which was familiar, and yet he could remember no individual occasion. He must have done this a hundred times before, begun with a crime, then learned experience by experience to know the people and their lives, their tragedies.

How many of them had marked him, touched him deeply enough to change anything inside him? Whom had he loved- or pitied? What had made him angry?

He had been shown out of the front door, so it was necessary to go around to the back areaway to find Evan, whom he had detailed to speak to the servants and to make at least some search for the knife. Since the murderer was still in the house, and had not left it that night, the weapon must be there too, unless he had disposed of it since. But there would be many knives in any ordinary kitchen of such a size, and several of them used for cutting meat. It would be a simple thing to have wiped it and replaced it. Even blood found in the joint of the handle would mean little.
