‘I’ll wait,’ Rico said feverishly, and began to back away.

Baird caught hold of his coat front and shook him.

‘Don’t run. If you want your share, you’re damn wel going to earn it!’

He gave Rico a shove that sent him reeling into the shadows.

‘Don’t leave me!’ Zoe screamed, struggling to sit up. ‘Rico! Don’t leave me with him! Rico! Come back!’

Rico blundered down the stairs, sweat pouring down his face. Zoe’s screams suddenly stopped and, shuddering, Rico began to grope his way along the pitch-black passage. The darkness came down on him as if a blanket had been thrown over his head. He could see nothing, and he stopped short, his heart pounding, while he tried to see where he was going.

He remembered the huge spiders, and stinking refuse on the floor and the rats, and he knew he couldn’t go on without a light. He turned and groped his way back until he reached the steps. He sat down, holding his head between his hands.

It seemed to him he sat in the evil-smelling darkness for a long time. Somewhere in the passage he could hear the busy gnawing of rat’s teeth on wood, the occasional drip of water, and the persistent patter of the rain against the walls of the building. But he didn’t pay any at ention to these noises. His ears were straining for the sound of any activity in the vast room above him. At first he heard nothing, then he imagined he heard the sound of breathing until he realised it was the curious echo of the thumping of his own heart as he sat there, his blood hammering through his veins.

The minutes dragged by. What could Baird be doing? he wondered stupidly. Perhaps after all she was talking, telling Baird what he wanted to know, and it would mean…

A long, blood-chilling scream rang suddenly through the building. It came down to Rico like the rush of wind, past him, and on down the passage, making the rats scramble up the walls in a panic of agitation.
