“Not very efficient,” Farnham countered. “They wouldn't go if they didn't believe they'd be the ones who'd get away.”

“Then he'd simply kill one of the others,” Monk explained, watching Farnham's face. “One of the younger, more vulnerable ones, whoever the escapee was most fond of.”

Farnham paled, and started to swear, then bit it off.

“It's more than that also,” Monk went on. “Have you considered, sir, what kind of men his clients are?”

Farnham's lips curled; it was a subconscious expression of revulsion. “Men with obscene and uncontrolled appetites,” he replied. “The use of street women may, by some stretch of the imagination, be understandable. The abuse of terrified and cowed children is not.”

“No, sir, it's not,” Monk agreed vehemently. “But that was not the aspect of them that I was thinking of. They are deplorable, but Phillips's clients are also rich, or they couldn't pay his prices. It's not a brothel he runs, it's entertainment, costumes, charades, photographs. They pay well for it.”

“Your point, Monk? We know Phillips profits. That's why he does it. It's hardly worth making a point of.”

“No, sir,” Monk said urgently. “That's only part of the reason. Perhaps even more important than that is its power.” He leaned forward a little, his voice becoming sharper. “They are important men, some of whom hold high office. They know their appetites are not only twisted, but because it is boys, they are also criminal.” He saw a hideous understanding dawn in Farnham's eyes. “They are highly corruptible in all sorts of other ways, sir. Have you never wondered why Durban couldn't catch Phillips before? He was close many times, but Phillips always got away. Oliver Rathbone conducted his defense, but who hired him, do you know that? I don't, but I would dearly like to.”

“It could be…” Farnham stopped, his eyes wide.

“Yes, sir,” Monk finished for him. “It could be almost anyone. A man in bondage to a devil inside himself, and a monster like Phillips outside, is capable of all manner of acts. He could lie at the heart of our justice, our industry, even our government. Do you still want me to forget about Phillips, and concentrate on warehouse robberies, and the odd theft from cargoes on the water?”

“I could tell this damn journalist this,” Farnham said very quietly. “God knows what he'd do with it. He's saying now that the corruption in the River Police is deep and lasting, and that the public has a right to know exactly what it is, and where it leads. He's even suggesting, so far only verbally, but print will follow, that we should cease to exist as a separate body at all but be broken up and come under the local stations. Our survival depends on this, Monk.”

“Yes, sir. I've heard rumor of it already. But then he may be one of Phillips's customers, or in the pay of one.”

Farnham looked as if Monk had slapped him, but he did not retaliate. It was himself he was furious with, because he had not thought of it. “He even put up the possibility that Durban was a partner in Phillips's trade,” he said bitterly. “And his pursuit of Phillips was in order to take over all of it. That's what he'll write, if we don't find a way of stopping him.” His shoulders hunched tightly, as if every muscle in his body were knotted. “Tell me, Monk, don't leave me defenseless when I talk to this bastard. What did you find out about Durban? We can't afford dignity now, for the living or the dead. I won't tell him, but I need to know, or I can't defend any of us.”

Monk weighed his trust and his loyalties. He needed to trust Farnham, for the sake of the future. “He lied about his family, sir,” he admitted. “Said his father was a schoolmaster in Essex. Actually I don't think he knew who his father was. His mother died in a foundling hospital, giving birth to him. He grew up there. He was put out in the streets to earn his own way when he was eight. That's why he had such compassion for mudlarks and other children, or women on their own, the hungry, the frightened, the abused. It was fellow feeling. He'd known it himself.”

“Oh, God!” Farnham ran his hands through his sparse hair. “Any crime known against him? And tell me the truth, Monk. If I get caught in a lie just once they'll never believe me again.”

“Not known, sir,” Monk said reluctantly. “But friends of his robbed a bank. Bad associates. Growing up in the streets, that's unavoidable. It was just after that that he joined the River Police.”

“Thank God. Now who is this Mary Webber he was hell bent on finding? Childhood sweetheart? Common-law wife? What?”

“Sister, sir. Older sister. She was adopted, but the family who took her, the woman was crippled and couldn't cope with a baby, so he was left behind. Mary used to save up pennies and send them to him. They lost touch when she married and later discovered her husband was a thief. She was too ashamed to let Durban know that. The hospital gave him the name of Durban, after one of their benefactors who happened to be from Africa. She changed her name when she married, and then again when her husband's creditors came after her.”

“Where is she now?”

“I know, but it's irrelevant, sir. She's safe, for the time being.”

Farnham blasphemed gently. “I apologize, Monk. You did a superb job finding out about Durban. I hope nobody but me ever has to know about it. I'll put a flea in this newspaperman's ear that will keep him busy, and far away from us for as long as possible. If he speaks to you, tell him you are under orders, on pain of losing your job, to say nothing. Do you understand?”

“Yes, sir. Thank you.”

“You'll keep me informed?”

“Yes, sir.”

Monk told Orme briefly what Farnham had said, and was only just outside the station walking towards the stairs down to where the police boat was waiting when a man approached him. He was ordinary, slightly shambling, impossible to describe so he would be known again. He wore an old seaman's jacket, shapeless enough to hide his build, and a cap on his head, which hid his hair. His eyes were narrowed against the bright light off the water.

“Commander Monk?” he said politely.

Monk stopped. “Yes?”

“Got a message fer yer, sir.”

“From whom?”

“Din't give me no more, sir. Said as yer'd know.” The man's voice was innocent, even courteous, but there was something knowing in his manner, and the creases that almost concealed his eyes suggested a sneer.

“What's the message?” Monk asked, then half wished he had refused to listen. “Never mind. If you can't tell me who it's from, maybe it doesn't matter.”

“Gotta deliver it, sir,” the man insisted. “Paid ter do it. Wouldn't reckon my chances if I mess wi’ this gentleman. Nasty, he would be, real nasty… if yer get my meanin’?” He looked up at Monk and he was definitely smiling now. “Glad ter see yer listenin’, sir. Save my neck maybe. Gentleman said ter tell yer ter back off the Durban case, whatever that is? D'you know?” He lifted an eyebrow. “Yeah, I can see yer do. ‘E said it would be best people think like they do, ‘cause Durban did wot ‘e did. Otherwise, this gentleman said ‘e'd make the ‘ole thing public. Said ‘e ‘as all the evidence that yer took on this Durban 's job wi’ the police, wi’ all ‘is papers and things. An’ yer took over ‘is other interests an’ all, the business o’ getting little boys, that is. Yer got one special trained up fer yerself, an’ all. Clean and bright, ‘e is. Go down a treat wi’ certain gentlemen wi’ special tastes. Scuff, I think ‘e called ‘im. That sound right to yer, sir?”

Monk felt sick to his stomach, his body cold. It was obscene, as if a filthy hand had reached out and touched everything that was decent and precious, staining them with its own dirt. He wanted to lash out at the man, hit him so hard he broke that leering face and left it a bloody pulp so he would never smile again, never speak clearly enough to say words anyone could distinguish.
