An author and historian will reveal shocking details about Jack The Ripper's links to East Yorkshire in a series of lectures.
Mike Covell, who has been researching the killer for six years, will discuss ten suspects in the case and their connections to the region.
He will also talk about a letter that was sent to Hull Daily News on October 6, 1888, chillingly signed "Jack The Ripper".
Mr Covell, 31, of east Hull, said: "I have a heart condition and I'm unable to work, so I needed to take on a hobby.
"I had read a few books about Jack The Ripper but wanted to research the murders and the suspects in more detail.
"It spiraled from there and I have three lectures booked for this year in both Hull and Beverley.
"People are still interested in the case because it was never solved and nobody ever found out who Jack The Ripper was.
"A lot of people have their own theories but I don't really have one. I just enjoy learning about the links to Hull.
"I've never given the same lecture twice and there is a lot of new information this year for those interested in his Hull links.
"I reveal everything from silly facts to multiple murderer and bigamist Frederick Bailey Deeming, who was a suspect. He lived in the city for a while and robbed a jewellery shop in Hull.
"The letter, which was sent to the Hull newsroom, said Jack The Ripper was coming to Hull and he had a new knife.
"There are plenty of things I will be talking about in the lectures that will make the audience gasp.
"People are often quite shocked that there are so many links to Hull."
Mr Covell scoured through old copies of the Mail to find out information and, at times, his search for the truth turned international.
With the ongoing series Ripper Street on BBC One, Mr Covell said the murderer is a hot topic once
again. The mini-series is set in Whitechapel in London's East End in 1889, six months after the infamous murders.
"As a 'Ripperologist', this got me very excited," Mr Covell said. "For months I would count down until showing, readying my Sky planner to record the series in HD and hoping that a DVD release would soon follow.
"The buildings and costumes looked amazing and the over-populated grime-ridden back streets of Whitechapel were really well done.
"People are interested in the murders but it's also important to remember the victims and their families.
"Talking about the murders and what happened is also a way of remembering those who died."
Mike's Jack The Ripper lectures will be held on three dates.
The first is at Hull Central Library on Tuesday, January 22, from 1.30pm.
It will be followed by a lecture at Ings Library in east Hull on Tuesday, February 5, and another in Beverley in September.
