AS concerned Derek Joyner tried to find out why his partner, Sandra Bainbridge, was not answering his calls, he came face to face with her psychotic killer.
Derek called at Sandra's corner terraced cottage in Belper and was shocked to find no sign of her and a chaotic scene in the kitchen.
As he checked rooms upstairs, he was startled when a door opened a few feet away and a sinister woman, dressed all in black, looked out at him.
Stunned Derek, 70, then saw the woman lean back into the room and pick up a butcher's knife. He grabbed the door handle and pushed it shut but could feel the woman trying to turn the handle and was aware he was losing the battle to keep it closed.
A terrified Derek turned and fled down the steep cottage stairs, flung shut the door at the bottom behind him and ran out of the house. He was unaware Sandra had already been stabbed to death by the intruder and her body lay in the back yard.
Agonisingly, after police found the body, Derek was arrested as a suspect before the real killer, psychotic Andrea Cutler – who had by then fled – was tracked down. She has now been sentenced at Nottingham Crown Court to be detained indefinitely under the Mental Health Act.
Derek and Sandra had just got back from a week's holiday in Turkey. Derek, who lives in Milford, was unaware that Cutler had taken over Sandra's Belper home while they were away and had killed her when she returned.
Retired teacher Derek recalled the terrible moments in December 2013. He said: "Just the day before we were on the beach in Turkey being 17-year-old 70-year-olds, kissing for a photographer."
But sitting on a wooden bench in a cell at Derby's main police station, as Derek tried to make sense of the terrible events, he held his head in his hands and wept.
He had endured a full body examination and had his fingerprints taken. In three hours' time he was to be questioned under caution for the murder of the woman he loved. How could this be?
"I was in complete shock," said the grandfather. "I was thinking 'this isn't happening, this is crazy'.
"I said to the officer as I was handcuffed, 'this is unbelievable. I have just been round to Sandra's, because I was concerned about the woman I love, and then here I am accused of murder. I could have been stabbed to death myself.'"
When asked by officers if he would like anyone to be informed about his whereabouts, he said no.
"It seems silly now," said Derek, "but at the time I felt so ashamed for being arrested for murder. Also, I started to think 'how can I prove I am innocent? I have spent most of the day on my own.'"
Derek never did have to prove his innocence. At 9am that morning he was released without charge after Cutler – who had fled in Sandra's car – was arrested in Manchester.
Until two months ago, when Cutler pleaded guilty to manslaughter, Derek had not been allowed to talk to anyone about the details of that horrific night because he was a key witness in the case. He was also kept in the dark about what had happened in Sandra's house before he went over to check she was safe.
Sitting in his living room, Derek said: "That was quite difficult. It was very isolating."
Looking back on the events of December 10 he said: "That was the worst day of my life. There's never going to be anything that will be as bad as that. After it, I thought 'there's two ways you can go here – you can let this ruin your life or you can rebuild it'.
"Sandra was very good at looking at the positive side of things. She would say 'yes, I'm going through this, but I've got family and friends supporting me'. And so I took that view."
Among the pictures covering the walls of his living room are photos of Sandra, including one of them together, smiling, taken in Turkey the day before she died.
"That's how I remember her – smiling and laughing," he said looking up at her photographs.
"I cannot even picture what the attack would have been like. I'm glad I haven't got that visual insight and I'm glad I don't have any nightmares but I do wake up in the early hours thinking about the whole case."
Derek and Sandra had returned from Turkey at about 7pm on December 9, 2013. Sandra picked her car up from Derek's house and returned home to her cottage in Short Row, Belper. They had agreed to speak later the following day.
When Derek attempted to call her at 8pm on December 10, the number was not recognised.
Derek said: "I thought 'this is silly, I speak to her every night on the phone', and I then rang her mobile and left a message saying 'for God's sake ring me'."
He drove to her house, which was locked, but did not have her key on him, so he returned home.
After calling BT, he discovered Sandra's phone number had been changed and tried the new number but there was no answer.
"I was completely perplexed. I rang her mobile and said 'look Sandra, I'm getting really worried now. Please get in contact with me'.
"I was thinking 'why the hell would she change her telephone number?' I thought 'I'm not happy with this, I'm going there.'"
Having had a couple of glasses of wine, Derek chose not to drive but caught the bus and took the key. It was about 11pm. He knocked but there was no answer and so he let himself in.
"I saw the light on in the kitchen and thought 'she's working on the computer', and so I walked through the living room but when I got to the kitchen door I couldn't believe what I was looking at, because she's usually meticulous in the kitchen.
"It was chaotic – there were bin bags on the floor. There was a terracotta-coloured liquid covering the floor, with a few red patches in it. With hindsight I realise someone had made a very poor attempt at cleaning the floor and it was dried blood."
Some butcher's knives lay on the work surface.
"I think common sense should have told me at that point 'get the hell out of here and ring the police', but at the time I just thought she had had an accident."
Derek headed back through the living room and up the stairs, calling Sandra's name. As he did so, he noticed her suitcase was dumped at the bottom of the stairs.
"That should have sent alarm bells through my head as she was a meticulous woman, and would have taken a suitcase straight upstairs and unpacked."
Sandra's bedroom door was open and Derek looked in to find it "immaculate". He went into the bathroom, where there was a white towel hanging over the bath with fresh bloodstains on it. Then, just as he was heading out of the bathroom, the door to the spare bedroom opposite opened very slowly and through the gap he saw a woman, dressed all in black, standing there. "She looked very hard," he said. "At first, the thought going through my head was that a gang had broken into the house, taken it over and this woman is a front for them.
"The woman said 'Sandra has gone out'. My brain was saying 'you're in a very vulnerable position here'. I said 'who are you?', she said 'I'm a neighbour'.
"I know Sandra's neighbours. This woman looked so out of place, so creepy. I should have said 'okay, I'll try later' and just walked out but I just blurted out 'where is Sandra? What have you done with her?'.
"At that point, she turned slowly around and the door swung open a bit. She leant over the bed and then stood up and turned around and she had a butcher's dagger in her hand, and I can still picture how the light caught the blade, and I thought 'hell' and my brain went into automatic gear. Without even thinking about it, I slammed the door on her before she could get to me."
There was then a struggle, where they both pushed on the door handle from either side.
"I was thinking 'crikey, you're not holding this' and my brain was saying 'right, calm down. I've got to get down those stairs and have time to open the door at the bottom and shut it'. I knew there was rubbish at the bottom of the stairs and the stairs are very steep, and I knew if I slipped on the stairs with her behind me with the knife, I would have had it, especially knowing now how she had attacked Sandra – without a doubt I would have had it. There was nothing there that I could defend myself with.
"Andrea Cutler is not a big woman but my God she had some force behind her. Sandra wouldn't have stood a chance. I struggled, and I'm 13st and 5ft 11in."
Derek let go of the door handle and made a run for it.
He said: "I managed to get down the stairs and open the door and shut it. She came down behind me and was rattling the door handle. I was holding on for grim death. Then my brain suddenly said 'wait a minute the porch door opens into this door', so I managed to put my foot against the stairs door and open the porch door and push my weight against it and keep the stairs door closed."
He reached over and opened the front door and dashed out before turning around to hold on to the handle. The woman was right behind him – again struggling with the handle on the other side of the door. She eventually gave up and he watched as she walked back into the house shrugging her shoulders.
Derek then ran down the street opposite until he reached a well-lit area and called the police. He was told to wait where he was until a van with two officers arrived. Five minutes later, a group of armed officers arrived to search the house.
He said: "I was in shock. I couldn't believe what had happened because this was the stuff you see in movies, not real life. The police told me to get into the van because they were concerned I was getting cold.
"I then heard a message come across the police radio saying a woman's body had been found in the garden. What crossed my mind was that either the woman had committed suicide or the body was Sandra's. I think it was then that the officers decided to take me to Ripley police station, to get me out of the way.
"When I first got out of the house, I felt guilty because I hadn't seen Sandra and thought 'what if she is tied up in the bedroom and all you're worried about is saving your own skin'. I didn't know she had been dead for a day.
"The emotions I went through that night are indescribable. It must have been about midnight when we got to Ripley. We were there for at least an hour when a detective came in and said he was arresting me on suspicion of the murder of an unidentified woman and I was handcuffed."
But some hours later, before he was interviewed, he was told his story had been checked out and police had arrested a woman in Manchester in Sandra's car and he was to be released without charge.
He was taken home so he could change his clothes and then returned to the police station for a video interview.
Derek said: "I hadn't eaten for hours, I had had no sleep and I was mentally exhausted but I was determined that I was going to do what I could to make sure she was convicted. This woman is very dangerous. She needs putting away for a long time. The impression I got at the time was of a nasty, ruthless, calculating person. I was lucky to get away.
"I think that what happened to me reinforces the case that this woman is unsafe with a knife in her hands."
At 6.30pm on December 10, Derek was dropped off by police at his daughter's house. "I just broke down and wept," he said.
Derek, a retired teacher, met Sandra at a real ale group, which is part of Belper's University of the Third Age, in October 2009.
He says: "Sandra was funny and we just hit it off, although initially I thought 'what kind of woman drinks pints of ale?' and she thought I was a bit odd. We were as different as chalk and cheese. She was outgoing and I was an introvert but we just sort of played off each other.
"Sandra was a natural comedian, she would come out with these one-liners. She was a very intelligent woman and also very popular."
The pair visited art exhibitions, classical concerts and the cinema, played cards together and also spent time travelling. In 2013 they went to America for a month as well their holiday in Turkey.
"We were booked to go on holiday to Mexico in January last year. It was going to be the holiday of a lifetime. We had arranged for individual guides to look after us and take us round historic sites.
"On the day we should have departed, January 31, it was her funeral."
Derek feels angry that Cutler had caused so much devastation to so many people.
He says: "Sandra was a unique person. She brought joy to people's lives. And she got killed in her own home. It's crazy."
