Coulter did what any decent man would. He swore a string of curses at Phillips, and bent to help the wounded lighterman, gathering as much cloth as he could into his fist and holding it on the wound while Orme-who had followed Coulter-took off his jacket, then his shirt, folded the shirt into a pad, and held it, stopping the blood as much as possible.

The bargees had pulled Phillips out of the water, already opening the distance between them and the drifting lighter with the ferry alongside it. Whether they meant to or not, their weight and speed meant that they could not stop easily. Phillips would be around the curve of the river beyond the Isle of Dogs in fifteen or twenty minutes.

Monk looked at the lighterman. His face was ashen, but if he reached medical help he might still be saved. That was what Phillips was counting on. He had never intended to kill him.

The ferryman was stunned, not knowing what to do.

“Take him to the nearest doctor,” Monk ordered. “You, get rowing as fast as you can. Coulter, look after him. Orme, put your jacket on and come with me.”

“Yes, sir!” Orme snatched up his jacket, and stood ready.

The ferryman took up the oars.

Orme and Coulter very gently and awkwardly picked up the injured man and laid him in the bottom of the ferry, Coulter holding the pad over his wound all the time.

Monk went to the fallen oar of the low, flat-bottomed lighter, and gripped it with both hands, balancing his weight. The moment Orme was on board Monk began to pull away. It came to him more naturally than he had expected. He knew, from flashes of memory and things he had been told, that he had grown up in Northumberland around boats, mostly fishing and in bad weather lifeboats. The way of the sea was ingrained in his experience, some inner sense of discipline. One can rebel against man and laws, but only a fool rebels against the sea, and he does it only once.

“We'll not catch up with him!” Orme said desperately. “I'd tie the noose around his neck with my own hands, and pull the trapdoor.”

Monk did not answer. He was getting the weight and movement of the long oar right, and learning how to turn it to gain the greatest purchase against the water. At last they were going with the tide now, but then so were the barges, fifty yards ahead of them at least.

There was nothing Orme could do to help; it was a one-man job. He sat a little way over to the other side to balance Monk's weight, staring ahead, his uniform jacket fastened to hide as much as possible the fact that he now had no shirt. Certainly he would never wear that one again.

“They're longer than we are,” Monk said with determined optimism. “They can't weave through the anchored shipping, but we can. They'll have to go around.”

“If we go in between those ships we'll lose sight of them,” Orme warned grimly. “God knows where he could get to!”

“If we don't, we'll lose them anyway,” Monk replied. “They're fifty yards ahead now, and gaining.” He threw his weight onto the oar, and pulled it the wrong way. He knew the moment he felt the resistance that he had made a mistake. It took him more than a minute to get into the rhythm again.

Orme deliberately looked the other way, as if he had not noticed.

The barges swung wide around an East Indiaman anchored ahead of them, stevedores working on deck with chests of spices, silks, and probably tea.

Monk took the chance, veering to the port to pass between the East Indiaman and a Spanish schooner off-loading pottery and oranges. He concentrated on the regularity of his strokes and keeping his balance exactly right, and trying not to think that the barges were going over to the far shore now that they were out of sight. If they did, he might lose them, but if he did not take the chance to catch up, he certainly would.

He passed as close as he dared to the East Indiaman, almost under the shadow of her hull. He could hear the water slapping against her and the faint hum and rattle of the wind in the shrouds.

The moment he was back in the sun again he looked to starboard. The line of barges was nearer, no more than forty yards ahead. He controlled himself with an effort. Orme was straining forward also, hands clenched, shoulders tight. His lips were moving as he counted the barges, just to make certain they had not cast one adrift when they were out of sight.

The gap was still closing. They could not see Phillips, and Monk searched back and forth along the line of canvas coverings. He could be behind a bale or keg, under the canvas, or even have taken a bargee's coat and cap and at this distance look like one of them. It meant nothing. Still he wanted to see him and be certain that Phillips was there.

He would have to go on to the barges alone. One of them had to stay with the lighter, or they would have no way to take Phillips back. It was a long time since he had fought alone against a man with a knife. In fact, he was not sure if he ever had. He remembered nothing from the years since the accident. Would he find some instinct to fall back on?

Ten yards now. He must get ready to jump. They were passing into the lee of a clipper. The masts seemed to scrape the sky, barely moving, since the hull was too large and heavy to roll in the short, choppy water. The lighter skimmed the surface easily, then bucked the moment it hit the tide again, but now they were closing on the last barge very quickly. Four yards, three, two-Monk leapt. Orme swung over and took the oar.

Monk landed on the barge, swayed for a moment, then regained his balance. The bargee took no notice. It was all a drama playing out in front of him in which he had no part.

Since Monk was on the last barge, if Phillips had moved at all, it had to have been forward. Monk started towards the front. He stood warily on top of the canvas, moving from one shapeless mound to the next, altering his weight all the time, arms wide, footing precarious. His eyes moved from one side to the other, expecting surprise.

He was almost at the prow, ready to jump to the next barge, when he saw a flicker of movement. Then Phillips was on him, knife arcing high and wide. Monk kicked forward, low and moving sideways, almost overbalancing, then righting himself at the last instant.

Phillips missed his mark, expecting to strike flesh and meet resistance, but not meeting it. He teetered on one foot, whirled his arms wildly for an instant, and fell forward onto his knees, ignoring the pain of Monk's boot on his flesh. He lashed out again immediately, catching the very front of Monk's shin and ripping his trousers, drawing blood.

Monk was startled. The pain was searing. He had expected Phillips to be more taken aback, longer in recovering, a mistake he would not make again. He had no weapon but the pistol in his belt. He drew it now, not to shoot but to bludgeon. Then he changed his mind and kicked again, hard and high, aiming more carefully this time. He caught Phillips on the side of the head, sending him sprawling. But Phillips had seen it coming and moved back, and the impact was not so great.

Now Monk had to go forward, over the lumpy canvas, and he had no idea what was underneath it. The barges were all hit by the wake of a coal barge, sails set, passing upriver. They bucked and slewed, throwing the men off balance again. Monk suffered most because he was standing. He should have seen that coming. Phillips, younger and more agile, had. Monk swayed, staggered, and fell almost on top of Phillips, who twisted and squirmed away from him. He landed hard, feeling the kegs under the canvas bruise him, and the next moment Phillips was on top of him, arms and legs like steel.

Monk was pinned. He was alone. Orme might even be able to see what was happening, but he could not help, and the bargees were going to take no part.

For a moment Phillips's face was so close, Monk could smell his skin, his hair, the exhale of his breath. His eyes were glittering, and he smiled as he brought the knife up in his hand.
