“A mutiny?” Orme suggested with a lift of hope. “Maybe they killed him? One hit him with something, two others strangled him? That could be why the odd marks. Maybe it isn’t a rope at all? Could be boys’ shirts, all tied together.” He turned to face Monk, his features ghostly in the lantern light. “They’d have gone. We’ll never find them.” All the emotion of his unspoken meaning was in his face.

“No point in even looking,” Monk agreed. “Murder by persons unknown.” He took a deep breath. “But we’d better make certain. There’ll be rooms for them below, and a galley of some sort. They have to feed them.”

Orme said nothing.

They found the ladder down and descended to the deck below. Immediately it was different. The heavier, more fetid air closed over them, and the lantern shone on darker walls only a couple of feet away. Monk felt the sweat break out on his skin, and then chill instantly. His heart was knocking in his chest.

Orme pushed at the first door, but it held fast. He lifted his foot and kicked it with all his weight. It burst in, and there was a cry from behind it. He held the lantern higher and the yellow light showed four small boys, thin, narrow-chested, half-naked, and cowering together in the corner.

Monk wiped his hand over his face, forcing himself to focus.

“It’s all right,” he said quietly. “Nobody’s going to hurt you. Parfitt is dead. We’re going to take you away from here.” He stepped forward.

They all shrank farther back, flinching, though his hand was several feet away from the closest of them.

He stopped. What could he tell them that they could believe? They probably didn’t know anything but this. Where was he going to send them, anyway? Back into the streets? Some orphanage, where they would be looked after? By whom? Perhaps Hester would know.

“I’m not going to hurt you,” he repeated, feeling useless. They wouldn’t believe him; they shouldn’t. Perhaps they shouldn’t believe anyone. “Are there more of you?”

One nodded slowly.

“We’ll get you all, and then take you ashore.” Where to? How many boats would they need? It was night already; what was he going to do with them? A dozen or more small boys: frightened, hungry, possibly ill, certainly hideously abused. Then he thought of Durban, his predecessor, and remembered his work with the Foundling Hospital. “We’ll go where they’ll look after you,” he said more firmly. “Give you warm clothes, food, a clean bed to sleep in.”

They looked at him as if they had no idea what he was saying.
