Monk felt a tightening inside himself. A daughter, even as pretty and as charming and as seemingly agreeable as Zillah, was a source for all kinds of fears. Illness and accident were only the worst. There were so many humanly made, unnecessary other traps and snares, even in a young life barely begun.

"What is it?" Lambert repeated, not yet offering Monk a seat.

Monk had been considering where to begin. Lambert was a blunt man. He would not appreciate prevarication.

"I have been looking into Keelin Melville's death," he said directly, watching Lambert's face. "For Rathbone's sake as much as anything. It seems so..."

He saw the look of pain in Lambert's eyes.

"So oddly timed," he went on. "According to the police surgeon, she must have taken the poison while she was actually in the court, and yet she was observed all the time, and she neither ate nor drank anything at all. And why then, rather than later at home? Why would anyone choose to take poison in public in order to die in private, when doing both at home would have been so much easier?"

Lambert stared at him, puzzled and now also troubled. It seemed that up until now his emotions had crowded out thought. This came to him as an ugly intrusion, but he did not evade it.

"What are you trying to say, Monk? You are not a man to come here to see me simply to say there are things you do not understand. You have no need to understand, unless you believe there is something wrong, something criminal, or at the very least, something profoundly immoral. What do you expect of me?" He walked back to one of the chairs, not the one behind the desk but one of those arranged in front of it, and sat on it.

Monk sat in one of the others, crossing his legs and leaning back.

"One possibility troubles me, and I would like to prove it wrong before I let go of it."

"Yes? What is that possibility, and how does it concern me or my family?"

"I am not sure that it does," Monk admitted. "The possibility is that she was murdered."

Lambert leaned forward. "What?" He seemed genuinely not to have understood.

Monk repeated what he had said.

"Why?" Lambert puckered his face, his eyes narrowed. "Why would anybody want to murder Melville? He was the most..." He swallowed. "She was the most likable person. Of course, she had professional rivals, but people don't kill for that sort of reason." He waved his hand. "That's preposterous. And no one except Wolff knew she was a woman. You're not suggesting Wolff killed her, are you? I don't believe that for an instant!" Everything in his voice, his expression, emphasized what he said.

"No I don't," Monk agreed. "If it was murder, then I think it was to stop the case from going any further."
