The mother of a Kent man who was found dead in Poland wants an investigation into his untimely death.
Max Spiers, who was 39, and from Canterbury, had told her - "if anything happens to me - investigate. "
Mr Spiers travelled the world, fascinated by science and UFOs.
But as he got deeper into his subject, he became more and more convinced his life was in danger.
When the father-of-two was found dead, friends were convinced he'd been killed.
Now his MP has asked the Foreign Office to get involved and find out what they can about his last days in Poland.
Local authorities in Warsaw say he died from natural causes – but his mother has told reporters she has doubts over the verdict.
Vanessa Bates, an English teacher, said: "He was making a name for himself in the world of conspiracy theorists and had been invited to speak at a conference in Poland in July.
"He was staying with a woman who he had not known for long and she told me how she found him dead on the sofa.
"But I think Max had been digging in some dark places and I fear that somebody wanted him dead."
North East Kent coroner's office said that an investigation into Mr Spiers’ death was in its “very early" stages.
