Many officers would have seen this man as small-fry, almost harmless, but looking at him Mike knew the truth: when a person commits crime for fun, they can take it or leave it; but when a person commits crime because their life depends on it, they can become a killer in the blink of eye. If you don’t catch them in time, they can be the ones you read about in the news.

Ridley had attended Mike Haskin’s retirement party some months earlier and had spoken so highly of Mike’s dogged determination and unwavering self-belief, that Jack had remembered his name. Ridley had even mentioned the Alley Burglar case, explaining how Mike had stuck to his guns, even when his DI had lost faith in him. If Ridley had taught Jack anything over the years, it was to respect the talents of others and to be humble enough to surround himself with exceptional officers who shone in the areas that he did not. Ridley had wanted Jack on his team for this very reason, and now Jack wanted Mike on his.

DS Richard Stanford was personally grateful for their help on the Wimbledon Prowler investigation, but unlike Mike Haskin, he had struggled with the silent derision from others on the force because he hadn’t yet got his man. He knew it should be water off a duck’s back, but, for some reason, it cut deep. The Wimbledon Prowler case was becoming the bane of his life and, worse, he’d lost the enthusiasm of his men. On one occasion, a cocky little PC by the name of Denny McGinty had loudly fake-yawned during a morning briefing and Stanford had gone ballistic in frustration and embarrassment. That was the moment that his boss had called Ridley, and Ridley had called Jack.

Jack Warr and Mike Haskin sat quietly and patiently in front of Stanford as he laboriously laid out all of the details of the investigation. It was clear he’d done nothing wrong as such, he’d just lacked imagination and the ability to step outside the rather sterile and restrictive box of police procedure and into the dirtier, messier world of the career criminal.

‘Sir . . .’ Jack interrupted during one of Stanford’s pauses for breath. ‘Mike has been where you are, and he got his man. Now, he’s going to help us get yours.’ Jack smiled, making sure that his deep brown eyes smiled too. ‘When going forwards isn’t working, go back.’ For the first time since they’d arrived, Stanford dared to relax and sit down.
