“Well, try not to ruin him, would you? He still has a sense about these things. He was first on the scene again, did he tell you?”

Jackaby shook his head.

“Got a funny look on his face just as we neared the building. He yelled something about the fourth floor and bounded up the stairs three at a time. By the time we caught up with him, he was at their door, and that O’Connor woman was answering. She didn’t even know. She said she felt something was very wrong . . . but so did we all, I guess. She had been in the next room, and she didn’t even know what had happened until Cane pushed open that bedroom door. Hell of a sight. She let out a scream and just fell to pieces. Can’t say I blame her. Like I said, this sort of thing is not for the female temperament.” He directed that last sentiment at me, making eye contact for the first time.

“I dare say you’re right, sir,” I conceded, meeting his gaze. “Out of curiosity, though, is there someone whose temperament you do find suited to this sort of thing? I think I would be most unnerved to meet a man who found it pleasant.”

I wondered if Marlowe was going to tell me off for my forwardness, but he only grunted and shook his head. “Nothing pleasant about any of this.” He fell silent again for several seconds. Finally, he sighed, and his eyes cast upward for a moment before turning back to the door.

“Come on, then.” He trudged inside the building without any further explanation or invitation. Jackaby, not needing any to begin with, was right behind him, and I jogged through before the door swung closed.

I was alarmed to find Mona O’Connor still in her apartment. Someone had draped a thick quilt over her shoulders, probably the officer standing stiffly behind her, and she sat on the well-stuffed sofa, staring blankly into space. Her hair was disheveled, and several curly red locks hung across her face. She had the dull expression of one who has been scooped out entirely, and does not know what to do with the emptiness. No, not emptiness, exactly. Somewhere, through her eyes and deep inside the hollow, there was an ember of something just beginning to glow. It reminded me of Jackaby’s oblivious intensity, but with a far more dangerous edge about it.

“Should she be here?” I asked Marlowe in a whisper. “Wouldn’t it be kinder to take her away from . . . from the scene?”

The chief inspector nodded. “We tried.” His eyes darted to the officer, who, I noticed, had a bit of gauze wedged up each nostril, and a bluish bruise blossoming across the bridge of his crooked nose.
