The bridge was only two hundred feet away now. The couple were still there against the balustrade. The man held her by the shoulders as if he would take her in his arms. Perhaps they were lovers. Of course, Monk could not hear their words-the wind tore them from the couple's mouths-but their faces were alive with a passion that was clearer with every moment as the boat drew towards them. Monk wondered what it was: a quarrel, a last farewell, even both?

The police oarsmen were having to pull hard against the incoming tide.

Monk looked up again just in time to see the man struggling with the woman, holding her fiercely as she clung to him. Her back was to the railing, bending too far. Instinctively he wanted to call out. A few inches more and she would fall!

Orme, too, was staring up at them now.

The man grasped at the woman and she pulled away. She seemed to lose her balance and he lunged after her. Clasped together, they teetered for a desperate moment on the edge, then she pitched backwards. He made a wild attempt to catch her. She flung out a hand and gripped him. But it was too late. They both plunged over the side and spun crazily, like a huge, broken-winged bird, until they hit the racing, filthy water and were carried on top of it, not even struggling, while it soaked into them, dragging them down.

Orme shouted, and the oarsmen dug their blades in deep. They threw their backs against the weight of the river, heaving, hurtling them forward.

Monk, his heart in his mouth, strained to keep the bodies in sight. They had only a hundred feet to go, and yet he knew already that it was too late. The impact of hitting the water would stun them and drive the air out of their lungs. When at last they did gasp inward, it would be the icy water laden with raw sewage, choking them, drowning them. Still, senselessly he leaned forward over the bow, shouting, "Faster, faster! There! No ... there!"

They drew level, turning a little sideways. The oarsmen kept the boat steady in the current and the changing balance as Orme heaved the body of the young woman over the gunwale. Awkwardly, as gently as he could, he laid her inside. Monk could see the other body, but it was too far away to reach, and if he stretched he could tip the boat.
