“You’ve played your usual blinder,” said Strike, checking his watch. “Gotta go. Text me the details of this strip club, will you?”

“I thought I might—”

“No, I want you to stick to Wollaston Close,” said Strike. “Keep in touch.”

As the glass door closed behind him and he clanged away down the metal stairs, she tried to feel pleased that he had said she’d played a blinder. Nevertheless, she had hoped for a chance to do something other than stare pointlessly at the flats of Wollaston Close for hours. She was starting to suspect that Laing was not there and, worse still, that Strike knew it.

The visit to the lawyers was brief but productive. The solicitor was delighted with the copious evidence that Strike had laid in front of him, which vividly documented Mad Dad’s constant violations of the custody agreements.

“Oh, excellent,” he beamed over an enlarged picture of the youngest son cowering tearfully behind his nanny as his father snarled and pointed, almost nose to nose with the defiant woman. “Excellent, excellent…”

And then, catching sight of his client’s expression, he had hurried to conceal his glee at this vision of her child’s distress and offered tea.

An hour later Strike, still in his suit but with his tie now stuffed in his pocket, was following Stephanie into Catford shopping center. This meant passing under a gigantic fiberglass sculpture of a grinning black cat, which sat on top of the girder that spanned the alley leading into the mall. Two stories high from its dangling paw to the tip of its jaunty tail, which pointed skywards, it seemed poised to pounce upon or scoop up shoppers as they passed beneath.

Strike had decided to follow Stephanie on a whim, never having tracked her before, and intended to return to keep watch over the flat once he had satisfied himself as to where she was going and whom she might be meeting. She walked, as she almost always did, with her arms wrapped tightly around her torso, as though holding herself together, wearing the familiar gray hoodie on top of a black miniskirt and leggings. The slenderness of her twig-like legs was emphasized by her clumpy trainers. She visited a pharmacy and Strike watched through the window as she sat huddled in a chair waiting for a prescription, making eye contact with nobody, staring at her feet. Once she had collected her white paper bag she left the way she had come, passing back beneath the giant cat with its dangling paw, apparently returning to the flat. However, she walked straight past the chippy in Catford Broadway and shortly afterwards took a right at the Afro Caribbean Food Centre and disappeared into a small pub called the Catford Ram, which was built into the rear of the shopping center. The pub, which appeared to have only one window, had a wood-clad exterior that would have given it the look of a large Victorian kiosk had it not been plastered with signs advertising fast food, Sky Sports and a Wi-Fi connection.
