SICK speedboat killer Jack Shepherd is reportedly trying to cash in on the deadly drunk Thames crash that claimed his date's life with a vile ￡3.99 memoir written from behind bars.

       Charlotte Brown, 24, was tragically thrown from his boat when it capsized on the freezing River Thames in December 2015.

       Jack Shepherd - who was jailed in 2018 - has reportedly written a book about the tragedy

       Shepherd had been drinking heavily before the shocking incident, while English literature graduate Charlotte barely touched a drop on their first date.

       In harrowing footage, Charlotte - who died shortly after hitting the river from cold water immersion - could be heard screaming: "Oh my God, you're going so fast."

       Shepherd was sentenced to six years in prison in 2018 after being convicted of manslaughter in his absence.

       But the remorseless killer has reportedly published a book about the horror incident that spells out his warped version of events, according to the Daily Mail.

       According to the outlet, he has been secretly penning the book in his cell with the help of his best friend during jail visits - which they hope to use to make money by flogging it for ￡3.99 using Amazon’s online Kindle store.

       And to get around legal question marks as the law prevents criminals from profiting off memoirs, the pals have decided to label the book as a "work of fiction".

       They have simply changed the names of the people and places involved to jump through legal hoops, according to the Mail - with Jack's swapped to Keith and his friend's to Clive.

       The original working title of the 207-page book was My Mate The Speedboat Killer, with it describing Shepherd's use of Class A drugs and "womanising".

       A version of the sick memoir that details the fatal crash has now been self-published on Amazon for Kindle readers.

       The Prison Service has insisted that inmates are "never allowed to profit from their crimes" and that any action necessary is taken to prevent it.

       But it's not the first time ex-web designer Shepherd has tried to cash in on the tragedy.

       He previously tried to negotiate terms for a Netflix film about the fatal crash.

       Story Films decided to stop pursuing the project after the BBC rejected their proposal.

       Shepherd, was jailed for six years over Charlotte's death, but he originally went on the run ahead of an Old Bailey trial and spent ten months in Georgia, from where he was later extradited.

       Charlotte died on her first date with Shepherd during a boozy late night jaunt in the speedboat he bought to “pull women”.

       Shepherd’s UK case sparked outrage when The Sun revealed he won taxpayer-funded legal aid to appeal his conviction while on the run for ten months.
