As if aware of it, she turned and answered as though it were Runcorn who had elaborated rather than Monk. "We were at the theater that night," she told him. "I can't remember what we saw, and it doesn't matter now. It went right out of my head when I heard the next day what had happened. But we did return about half past midnight, and we saw a man coming out of the mews opposite."

"He wasn't coming out," Barclay contradicted her with a wince. "He was on the footpath, staggering around. He had clearly been overindulging. I've no idea who he was, so I couldn't tell you where to find him. But even if I could, he would be useless to you. He couldn't even see where he was going, let alone be a credible witness to anything." His brow furrowed, his expression sharper. "But even if he'd seen Havilland put the gun to his head and pull the trigger, how would that help anyone? You know what happened. Let it be mercifully forgotten. It's no one's fault, and nothing whatever to do with us."

Monk was freezing. His body and Runcorn's were to some extent sheltering Barclay and his sister, but even so he felt a stiffening of anger, a heat of resentment rise inside him. "It is possible, sir, that Mr. Havilland did not kill himself!" he said sharply.

"Don't be absurd!" Barclay was angry now, rattled. "Are you suggesting there's some maniac going around shooting people in their own homes, in the middle of the night? Here?" He put his arm out as if to protect his sister.

She moved fractionally away from him, just out of his reach, her eyes still on Runcorn.

It was Runcorn who answered, not to contradict Barclay so much as to reassure Melisande. "No, sir. If it was someone else, then it was deliberately planned and arranged, and it was to do with his work. There is no need at all for anyone else to be alarmed. If we are right, then the man concerned is miles away from here, and the last thing he'd be likely to do is draw attention to himself by coming back."

Melisande smiled. "Thank you," she said quietly. "And he did come out of the mews. He staggered around a little as if he was drunk, and he said he was."

"He said he was?" Runcorn was startled. "What did he say, exactly?"
