Wallis had shot Malone dead when he thought the guy was about to attack him. But there was a bit of a rumpus because Malone’s girlfriend – who sadly miscarried during the raid – later claimed that Malone had not posed a threat, and that the officer had fired the three fatal shots because he panicked.

An investigation cleared Wallis and accepted that the action he took upon entering the couple’s bedroom that night was justified.

But the decision caused a ripple of alarm within the criminal community and the word on the street was that Roy Slack’s people had been using their contacts to try to find out the identity of the officer, which hadn’t of course been made public.

Personally I had my doubts that Slack would be so stupid as to seek retribution against the police, especially on behalf of someone who was fairly low down the food chain within his organisation.

But as we would soon discover, the man was far more ruthless than his reputation had led us to believe.

And he had secrets that would turn out to be just as shocking as his actions.

Slack

It didn’t take long for Roy Slack to reveal his plan to Danny Carver. It was a simple one, after all.

Danny’s reaction was predictable. His jaw dropped and the colour retreated from his face.

‘Is this a fucking joke, boss?’ he said, his voice stretched thin with shock. ‘Because if it ain’t, then I think you might have lost your marbles.’

Slack stood up and stepped out from behind his desk. It was uncomfortably warm in the office so he slipped off his cardigan and threw it on the chair. His white shirt had dark patches of sweat under each armpit.

He crossed the room to the cabinet with the bottles of spirits on top.

‘Care for a whisky, Danny?’ he asked.

‘Too bloody right I do,’ Danny answered. ‘And please make it a large one because I think I need it.’

Slack smiled to himself as he poured out triples of his finest malt, flown down from his favourite distillery in the Highlands.

He handed a glass to Danny. ‘You’ve been with me a long time, mate, and you’re the only person in this world who I’d trust with my life. It’s why I’ve told you what I intend to do and it’s the reason I’m now going to tell you why I want to do it.’

Danny’s hard face fisted into a frown and he rolled out his bottom lip.

‘Well, I’m all ears, boss,’ he said.

Slack sat down beside him on the sofa and sipped at his whisky.
