Pitt could not detect even fear, let alone the conscience of a brutal murderer.
Wrexham wove in and out of the thinning crowd. Twice they lost sight of him.
“That way!” Gower gasped, waving his right hand. “I’ll go left.” He swerved around a window cleaner with a bucket of water, almost knocking the man over.
Pitt went the other way, into the north end of an alley. The sudden shadows momentarily made him blink, half blind. He saw movement and charged forward, but it was only a beggar shuffling out of a doorway. He swore under his breath and sprinted back to the street just in time to see Gower swiveling around frantically, searching for him.
“That way!” Gower called urgently and set off, leaving Pitt behind.
The second time it was Pitt who saw him first, and Gower who had to catch up. Wrexham had crossed the road just in front of a brewer’s dray and was out of sight by the time Pitt and Gower were able to follow. It took them more than ten minutes to close on him without drawing attention. There were fewer people about, and two men running would have been highly noticeable. With fifty yards’ distance between them, Wrexham could have outrun them too easily.
They were in Commercial Road East, now, in Stepney. If Wrexham did not turn they would be in Limehouse, perhaps the West India Dock Road. If they went that far they could lose him among the tangle of wharves with cranes, bales of goods, warehouses, and dock laborers. If he went down to one of the ferries he could be out of sight between the ships at anchor before they could find another ferry to follow him.
Ahead of them, as if he had seen them, Wrexham increased his pace, his long legs striding out, his jacket scarf flying.
Pitt felt a flicker of nervousness. His muscles were aching, his feet sore despite his excellent boots—his one concession to sartorial taste. Even well-cut jackets never looked right on him because he weighted the pockets with too many pieces of rubbish he thought he might need. His ties never managed to stay straight; perhaps he knotted them too tightly, or too loosely. But his boots were beautiful and immaculately cared for. Even though most of his work was of the mind, out-thinking, out-guessing, remembering, and seeing significance where others didn’t, he still knew the importance of a policeman’s feet. Some habits do not die. Before he had been forced out of the Metropolitan Police and Victor Narraway had taken him into Special Branch, he had walked enough miles to know the price of inattention to physical stamina, and to boots.
Suddenly Wrexham ran across the narrow road and disappeared down Gun Lane.
“He’s going for the Limehouse Station!” Gower shouted, leaping out of the way of a cart full of timber as he dashed after him.
Pitt was on his heels. The Limehouse Station was on the Blackwall Railway, less than a hundred yards away. Wrexham could go in at least three possible directions from there and end up anywhere in the city.
But Wrexham kept moving, rapidly, right, past the way back up to the station. Instead, he turned left onto Three Colts Street, then swerved right onto Ropemaker’s Field, still loping in an easy run.
Pitt was too breathless to shout, and anyway Wrexham was no more than fifteen yards ahead. The few men and one old washerwoman on the path scattered as the three running men passed them. Wrexham was going to the river, as Pitt had feared.
At the end of Ropemaker’s Field they turned right again into Narrow Street, still running. They were only yards from the river’s edge. The breeze was stiff off the water, smelling of salt and mud where the tide was low. Half a dozen gulls soared lazily in circles above a string of barges.
Wrexham was still ahead of them, moving less easily now, tiring. He passed the entrance to Limehouse Cut. Pitt figured that he must be making for Kidney Stairs, the stone steps down to the river, where, if they were lucky, he would find a ferry waiting. There were two more sets of stairs before the road curved twenty yards inland to Broad Street. At the Shadwell Docks there were more stairs again. He could lose his pursuers on any of them.
Gower gestured toward the river. “Steps!” he shouted, bending a moment and gasping to catch his breath. He gestured with a wild swing of his arm. Then he straightened up and began running again, a couple of strides ahead of Pitt.
Pitt could see a ferry coming toward the shore, the boatman pulling easily at the oars. He would get to the steps a moment or two after Wrexham—in fact Pitt and Gower would corner him nicely. Perhaps they could get the ferry to take them up to the Pool of London. He ached to sit down even for that short while.
Wrexham reached the steps and ran down them, disappearing as if he had slipped into a hole. Pitt felt an upsurge of victory. The ferry was still twenty yards from the spot where the steps would meet the water.
Gower let out a yell of triumph, waving his hand high.
They reached the top of the steps just as the ferry pulled away, Wrexham sitting in the stern. They were close enough to see the smile on his face as he half swiveled on the seat to gaze at them. Then he faced forward, speaking to the ferryman and pointing to the farther shore.
Pitt raced down the steps. His feet slithered on the wet stones. He waved his arms at the other ferry, the one they had seen. “Here! Hurry!” he shouted.
Gower shouted also, his voice high and desperate.
The ferryman increased his speed, throwing his full weight behind his oars, and in a matter of seconds had swung around next to the pier.
“Get in, gents,” he said cheerfully. “Where to?”
“After that boat there,” Gower gasped, choking on his own breath and pointing to the other ferry. “An extra half crown in it for you if you catch up with him before he gets up Horseferry Stairs.”
Pitt landed in the boat behind him and immediately sat down so they could get under way. “He’s not going to Horseferry,” he pointed out. “He’s going straight across. Look!”
“Lavender Dock?” Gower scowled, sitting in the seat beside Pitt. “What the hell for?”
“Shortest way across,” Pitt replied. “Get up to Rotherhithe Street and away.”
“Where to?”
