Abbott pushed back the hood of his scene suit. The last time Fry had seen him at an incident, he’d had a shaved head. Now, his hair had begun to grow back in ragged patches, so that his skull looked like an old tennis ball that had been chewed by the dog.

‘Well, we’ve got a series of impressions in the soil within a two hundred-yard radius of the hut,’ he said. ‘Quite a lot of impressions, actually.’

‘Shoe marks?’

‘Well, sort of.’

‘I thought the rain would have obliterated them by now.’

‘In the usual way of things, yes – that’s what I would have expected, too. Light prints on soft soil like this would have deteriorated beyond use. But these prints are a bit different.’

‘Different how?’

‘The amount of weight behind the shoe marks has imprinted them deep enough into the ground to preserve them in the drier subsoil, where the rain hasn’t affected them so much.’

‘Weight? That makes such a difference?’

Abbott nodded, a knowing smile on his face. ‘This amount of weight does. That, and the fact the shoes in question were made of steel.’

Fry found herself starting to get irritated. She was too wet and uncomfortable to tolerate people playing games.

‘Steel? What on earth are you talking about, Wayne?’

‘Horses,’ said Abbott. ‘I’m talking about horses.’

Chapter Four

THERE WAS STILL a lot of processing to do, of course. With his prisoner safely in the hands of the custody sergeant at E Division headquarters in West Street, Cooper made his way reluctantly from the custody suite, dodging the rain to reach the walkway that led into the main building.

In the CID room, the rest of the team were hard at work over their paperwork. DC Luke Irvine and DC Becky Hurst had been given the desks closest to his. They were the newest members of E Division CID, and they made him feel almost like a veteran now that he was in his thirties. They were eager to impress, too – anxious to get every last detail right in their reports and case files before their supervisor saw them. He had to give credit to Diane Fry for that. She had the new DCs with their noses to the grindstone. No one wanted to get on the wrong side of her.

‘Hi, Ben. How did it go?’ called Irvine.

‘Great. A good result.’

‘Wish I’d been there.’

Irvine was a bit too eager, his face still reflecting his excitement in the job, even when he was buried under paperwork. That wouldn’t last.

As he stripped off his stab vest, Cooper felt the last of the tension fall away. Suddenly, he felt bored again. He stared out of the window at the rooftops of Edendale, dark with continuous rain. His mind drifted back two days to the previous Sunday, and he realized the source of his restlessness.
