It was as if pieces of a jigsaw were beginning to come together as Farook told them the only other time he had seen this woman was when, on the day of the murder, she was coming out of Foxley’s flat and he recognized her. She had seemed agitated.

‘What time was this?’ Tyler asked.

Farook said it was exactly five minutes to five in the afternoon. Tyler and Spencer knew this was close to the time on the parking ticket that had been found in Justine’s coat. It further supported her version of events when Farook said he saw her driving away and took her parking space. He gave a strange, guttural chuckle.

‘It was lucky because in that area it was always difficult to find somewhere to park.’

Spencer couldn’t believe how unemotional Farook was. If anything, he seemed to almost be enjoying the process. The only sign of nerves was the glistening sheen of sweat on his round face.

He did not raise his voice nor did he lift his head to look either of them in the eye as he began to describe the chilling events that followed.

Farook rang the bell of Foxley’s flat. He heard a dog barking, but he was certain Foxley was at home, not just because he had seen his ex-wife leaving, but that afternoon Foxley had asked him to deliver drugs.

Farook began to gesture with his hands as he described how Foxley seemed dazed and was holding the side of his head. He had said that his ex-wife had just hit him with a cricket bat. He had even shown him the bat. Foxley also seemed drugged because when they walked up the hallway, he lurched against a wall.

Farook chuckled horribly again as he described watching Foxley slide down the wall in the hall. Farook had picked up the dog and put it in the kitchen because it wouldn’t stop barking. Then he had gone into the bedroom and taken his clothes off, even removing his socks. When he came out of the bedroom Foxley was conscious, staring in horror as he tried to stand up and get out of the flat. That was when he had struck Foxley on the back of the head, then swung the bat again and given him an equally hard blow on the left side of his skull. Foxley had fallen to the ground and he had dragged him to the bathroom.

Tyler and Spencer sat listening as Farook seemed to take pleasure in describing every detail of the brutal act and its aftermath, even down to showering and dressing himself afterwards. The one mistake he had made was leaving the cut-throat razor.

Spencer slid his notebook over to Tyler. He had written the word: handcuffs. Tyler glanced at the note and looked back to Farook.

‘Mr. Farook, did you bring the cut-throat razor and the knife to Mr. Foxley’s?’

‘Yes, sir, I did.’
