CALUM MacDONALD and LUCY ADAMS

Amid all the bizarre allegations and innuendo about Angelika Kluk, one fact is undisputed: she had a married lover.

Martin Macaskill, 40, met Angelika when he was driving for a wealthy Russian family for whom she was working as a nanny. He called her his "aghrai", Gaelic for darling one.

Their affair, which lasted three months, was no secret. Mr Macaskill's wife Anne knew it was going on partly from intercepting text messages, and yet did not leave her husband.

In fact, Mrs Macaskill revealed that she and her husband believe in polyamory, a system that condones open relationships and loving many people at the same time. The love may be sexual, emotional or spiritual.

The phenomenon developed in the US but has since become increasingly popular in the UK.

The couple, who had been married for 12 years, had been trying to find a way of including Angelika in their lives when she was killed.

Ms Kluk's sister, Aneta, had already made it clear that she disapproved of her relationship with this older married man.

However, Ms Kluk's diary, excerpts of which were translated for the court, talked daily of her love for him, despite knowing he was married.

She wrote: "I have never missed anyone as much as I miss Martin, even though he was here just a short time ago. Marriage is a sacred thing but I have my feelings too. I don't want it to be a dream. I want it to be life. I want to live it with my eyes wide open. My love to you is yet so small and immature but it will grows stronger and understands more."

The relationship between Mr Macaskill and Ms Kluk raised the eyebrows of many, and her sister Aneta ultimately banned him from the memorial service.

Mr and Mrs Macaskill live in the village of Inverkip, Inverclyde, where rumours about the couple persist. They include unsubstantiated claims that they were involved in swinging, and also that Ms Kluk had offered to act as a surrogate for her boyfriend and his wife.

Mr and Mrs Macaskill returned from Majorca, where they had been on holiday in an attempt to patch up their relationship, the day before Ms Kluk disappeared.

When she failed to turn up for her job as a cleaner on Monday, September 25, Mr Macaskill raised the alarm and searched her bedroom at St Patrick's along with her sister.

He feared the worst from the outset, because he said Angelika, whom he called Angela, would not leave without telling him. They were close, and even when he was in Majorca they had telephoned and texted each other.

Speaking to The Herald before her body was found, he said: "It makes no sense at all. I mean the relationship between Angela and me is good.

"It is complicated by the fact that I am married, but that's a moral issue more than anything else. Never- theless, Angela was happy and she knew I was going to come and see her on Monday morning and there was no reason whatsoever for her to go. She has not just walked away."

When they checked her room they found all her personal effects in the room: her bank cards, handbag, laptop, flash pens, passport, flight tickets back to Gdansk.

Visibly distraught, he explained at the time: "We went through her clothes and found she doesn't have a jumper, she doesn't have a jacket, nothing at all. At about 10.30pm on Monday Aneta wanted to call the hospitals but I called the police instead.

"When the uniform officers came they brought a dog, which was too much for me."

Mr Macaskill spent the five days before she was found visibly distraught. Weeping in front of journalists, he made repeated appeals for information about Ms Kluk and in a very public show of loyalty, his wife handed out fliers with him in the local area.

To The Herald he made a plea: "Angela, whatever it is, just come back. If you can, come back. You know I love you. More than anything else, I just want you to be safe and well."

After her body was found, Mr Macaskill and his wife left flowers with separate messages at the gates of St Patrick's.

Mrs Macaskill wrote her own tribute to her husband's young girlfriend: "My life has been touched by an angel. I dearly wish God hadn't called you back."

Mr Macaskill wrote: "To my Angel, my little piekna. With you I felt sunshine. We made the moments last.

"I will always love you and you will always be in my heart."

Last night Mr Macaskill spoke of his love for Ms Kluk. In an interview with BBC Scotland, he said: "Her enthusiasm for life and absolute passion for everything, passion for learning, enthusiasm for everything she came across was infectious, it was wonderful to see.

"She was just one of the people who shone."
