Monk shinned awkwardly up the bales, more slowly than Phillips, and reached the top with relief. He crawled over to the far edge and looked down. It was a long drop, perhaps fifteen feet. Phillips was in the distance, making for more mounds of cargo, casks of wine, cases of spice or tobacco.

Monk was not going to risk the jump. A broken ankle would lose him Phillips altogether. Instead he lowered himself, clung for a moment by his hands, then let go and fell the rest of the way. He turned and sprinted, reaching the casks of wine just as Phillips bolted across an open patch of stone towards the shadowed overhang of a cargo ship moored close up to the wharf. Its ropes were trailing, a crane beside her, a load of timber being lowered as they watched.

A horse-drawn wagon moved closer, wheels rumbling on the uneven stone. A gang of lumpers was walking towards the crane. A couple of idlers argued over what looked like a piece of paper. Everywhere there was noise: men shouting, the cry of gulls, the clang of chains, the creak of wood, the constant slap of river water against the stone. There was the incessant movement of the sun reflected on the water, sharp and glittering. The huge moored ships rose and fell. Men in grays and browns toiled at a score of tasks. Smells filled the air: river mud thick and sour, the harsh cleanness of salt, the sickly sweetness of raw sugar, the stench of hides and fish and ships’ bilges, and, a few yards ahead, the bewitching perfume of spices.

Monk took a chance. Phillips wouldn't try for the ship; he would be too exposed as he went up the side, like a black fly on a brown wall. He would head the other way, and disappear into the alleys.

Or would he bluff? Double bluff?

Orme was on Monk's heels.

Monk headed towards the alley entrance between the warehouses. Orme drew in a breath, and then followed him. The third policeman stayed on the quayside. He had done this sort of thing often enough to know men could double back. He would be waiting.
