The moment Neville saw the Commissioner's grave face, he knew Patterson had worked it out; the Commissioner was an experienced police officer, and Neville had seen that he hadn't lost his edge over some of the cases they'd worked on. "You already know," Neville breathed, mentally praying that was the case.

Patterson looked at him with sad inscrutable eyes. "I am so very sorry, Inspector," he said.

"You know it was Sophie, then," Neville whispered, shaken and heartbroken.

"Come with me. I've managed to get you released," the Commissioner said.

Neville was more than happy to go with him. Outside in the corridor, he found that Patterson had not come alone; she might have looked tired and wired, but Naomi still looked smart and efficient as always. She tried offering him a smile when she saw him, but it was spoilt by the pity and sadness he saw in her eyes.

"Hello, Inspector," she said.

"Hi, Naomi," he replied, drinking in the sight of her. It was good to be out of that cell.

"Where is she?" Neville asked as they went down the corridor. "Where's Sophie?"

Naomi paused and handed him a file he hadn't even noticed she was carrying. "Sophie Chambers doesn't exist. Her real name is Rebecca Wanslow."

Neville gaped at her, and he snatched the file and opened it. Quickly he found himself looking at a photograph of Grace Wanslow standing close to another girl who Neville had come to know, or thought he'd known very quickly.

It was Sophie.

"Sophie-Rebecca, she's Grace Wanslow's sister," Neville found himself whispering, suddenly seeing the full extent of the plan, and he fought the urge to rip his hair out in clumps at how stupid he was as his mind flashed to their meetings; that encounter outside the airport, their bags switching, that was just too convenient.

"Yes, Inspector. Both of them grew up in care without any other relatives. According to the file, both of them have criminal records. Like Miranda Priestly, they both began low-level drug dealing and courier work," Naomi cursed herself when she saw the poor man flinch at the mention of Miranda Priestly; it hadn't taken her long before she had worked out Neville had strong feelings for DS Cassell before she'd left, and now she'd brought it up after discovering his new girlfriend was a murderer who'd wanted him to pay for her sister's death.

"So that's why she came to Saint Marie," Neville said distantly to distract himself from the agony that he felt as they got into the Commissioner's car, "she wanted to get revenge….that meeting at the airport was an accident, must be, but the way our bags were swapped over, and the meetings since. It was all a great big con," he finished with a heartbroken sigh. He noted the concerned looks he was getting.

"I worked it out, how she killed Cartwright," Neville went on. "

"How?" Naomi asked.

"She was with me when I found his book outside the shack with his signature in it. She then followed me to the hotel with the knife, and she waited until I was gone and then got his attention. He let her in and she killed him. She cleaned the scene and left the same way, replacing the keys to the window as she did, so everyone would assume I had killed him by entering through the front door. Don't you remember; Sophie-Rebecca," he spat the name his fake girlfriend had used to throw off all suspicion of her, "was in the station when you arrested me, sir?" He turned to Patterson, who nodded gravely. "She exchanged the keys, so when that stupid DI who came to investigate me tried them out, they'd work. No problem. And she wouldn't have thought anything was out of place."

Neville leaned back, relishing the soft leather seat. "How did you figure it out?"

"We found out Cartwright had been visited by a fair-haired woman, in her 20s," Patterson explained. "And then I realised we'd gotten it wrong since your former colleague was accused of corruption in Manchester, and we took a look at Grace Wanslow's suicide. We found she had a sister," he gestured to the file.

"I trusted her, I'd even started to fall in love with her," Neville shook his head, fighting the urge to not open the car door and scream at the sky like a madman. Why was it that every time he got close to a woman, or thought he did, it blew in his face?

Zoe.

Florence.

Now Sophie, or rather Rebecca.

"Inspector, it was not your fault-," Patterson said.

"She treated me like a fool, sir. You know, when I tried to reassure you during that Aidan Shawcross case, I never realised how painful it was to be taken for a fool. But I do now," Neville lifted his gaze and sent an understanding look at his superior officer. "I do. Andy took a valuable piece of evidence right under my nose. I don't trust him anymore; he took evidence, lied, and he broke into my shack and cloned my phone; surely it occurred to him sooner or later you'd be called sir, and you would confront me about why they contacted you and why I haven't responded to them. But now I understand; Rebecca must have found something incriminating enough to get Andy investigated, and then she came here," he shook his head, stunned by the scale of the whole plan. A lot of it had probably been made on the go, there was no way she could have forced Cartwright to commit that murder while he smirked all the way, and…

Neville sighed and he fell onto the seat with a tired groan. He was so tired. He hadn't slept in his own bed for 3 days now, and he was exhausted and wasn't sure how much more he could take. "Where's Sophie now?" He whispered.

"I called Catherine; she's at your shack now. What do you want to do now, sir?"

Neville sighed again. "I want to sleep. I want to rest. I also want to get clean. I'm exhausted, and I know you are as well-."

"It's okay, sir," Naomi said sadly as she saw how broken he was, a man she admired greatly next to Marlon, Sammy, and the Commissioner as well as her own father. Neville Parker had taught her a great deal, and while he had many weird and sometimes irritating habits, he had won her respect. To see him so shattered… "You can wash up at my place if you'd like?"

"I don't want to put you out, Naomi," Neville sat up.

"You won't!" She said strongly before her face softened. "Please. You need rest. We all do. In the morning, we can get over to the shack and arrest her."

Neville nodded. "That sounds like a plan."

He fell asleep on the way to Naomi's place, though.

Author's Note - I enjoyed last night's Death in Paradise episode where Sophie was revealed to be the killer, and she had a fake name; for weeks fans have written about how something fishy was going on with her, but they didn't expect this. Me? I had to admit, there was something about how she didn't seem to feature much in the final episodes of this season, but I never never expected this.
