‘That’s where she’s going to be found,’ Dal as said, ‘and that’s where I’m going.’

Olin shrugged, but followed Dallas to the end of the alley into what appeared to be a cul-de-sac.

‘You won’t get to the river this way,’ Olin grunted.

Dallas swung his flashlight beam on the ground.

‘There’s been a car here. Look, tyre and oil marks. Where’s that lead to?’ He flashed his light on a low, dark archway. ‘Come on, let’s take a look.’

Olin followed him through the archway into an evil-smelling passage. In the mud and slush that covered the floor they could see footprints.

‘Someone’s been here, and recently,’ Dallas said.

He began to mount the stone steps at the end of the passage, stopped and sniffed.

‘Gunpowder!’ he exclaimed. ‘Can you smell it?’

‘Do you imagine I haven’t got a nose?’ Olin growled, jerking out his gun. ‘Get out of the way. I’ll handle this.’
