Marlowe delicately folded back the corner of the handkerchief in his hands, revealing the metallic sheen of the fork, and a crimson stain, which could only be blood. He made a show of thinking about the object for a few moments while Jackaby was shackled. “Don’t worry, Miss Rook.” He turned to me, flipping the cloth back over the tuning fork. “He won’t be leaving alone. I did warn you not to let him drag you into his craziness, didn’t I?”

Marlowe’s heavy, iron handcuffs were icy cold as he clicked them onto my wrists. As we drew into the lobby, we passed a small crowd of tenants being herded into the office by uniformed officers. A woman in a canary yellow dress made a point of alerting as many of her neighbors as she could nudge that we were passing through. They shuffled and watched our approach, in no hurry to be interviewed, but eager to eavesdrop. A reporter had set up a camera by the doorway, and he flashed a photograph as we arrived. Marlowe barked at him to put it away, and an officer crossed to block his view, but I tucked my head as deeply into my coat’s collar as I could, flushing with embarrassment. Jackaby, for his part, seemed unflappably comfortable, striding with as much confidence as if he were leading the policemen and not the other way around. The reporter didn’t try for any more photographs, but the nosy gossip in yellow had found her way over to him. She was stealing glances at us, and I saw her mouth form the words “that girl” with haughty disdain, before another figure burst from the milling crowd.

Mona O’Connor shoved past her neighbors and planted herself in front of Jackaby before any of the officers could intervene. She jabbed a finger into his chest accusingly. “You! You lied to me!”

“I assure you, Miss O’Connor, I did nothing of the sort. This is all a misunderstanding. If you don’t mind, we do need to be getting along.” His calm was mesmerizing, and if not for the cuffs jingling on his hands, I might have forgotten he was under arrest. Mona was not placated.

“You did! You lied to me!”

The guard on Jackaby’s arm attempted to position himself between the two, mumbling an ineffective, “Step back, please, madam. Out of the way. Step back.” An officer from the lobby came to assist, tugging at her arm. She jerked it away and persisted.

“You told me she would be better by morning!” she cried out as we began to move forward again.

Now Jackaby’s unflappable expression faltered. His eyes went wide and his brow creased. He attempted to stop, and the officer behind him gave him a shove. “Mrs. Morrigan?” he called over his shoulder as we were pressed toward the door. “You mean to say she isn’t?”
