WHO is the mystery woman who puts a smile back on Karl Kennedy's face on Neighbours? With his marriage in trouble will Karl play away from home?

Karl Kennedy (played by Alan Fletcher) and Susan's (Jackie Woodburne) marriage has run into trouble since all that deadly business with Finn Kelly on Neighbours (1:45pm/5:30pm on Channel 5, see our TV Guide for full listings).

Susan has been refusing to take doctor Karl's advice on board about her health. Plus she still feels he partly blames her for allowing Finn to move into the Kennedy house in the first place.

After their latest bust-up, Karl is drowning his sorrows at The Waterhole when he runs into an old flame, Olivia Bell (played by Alyce Platt, last seen on screen as Olivia back in 2012).

Simon has long been a fan of soap operas, and especially loves OVER-THE-TOP plots involving evil twins, hair-pulling catfights and natural disasters.

Anyone remember the Sunset Beach earthquake/tidal wave?

Simon has written for a variety of TV and childrens’ magazines/websites including Inside Soap, Nickelodeon, What’s On TV, Radio Times, Metro, Girl Talk, Disney Girl, Toxic! and Digital Spy.

He has reported LIVE from the red carpet at The British Soap Awards interviewing glammed-up stars from soapland, and hosted a Facebook LIVE session for Metro with Home and Away legend Ray Meagher (Alf "Stone the flamin' crows!" Stewart) to celebrate the 30th anniversary of the Aussie soap.

Simon is also co-author of The Treasures Of Coronation Street (Carlton Books)

And the writer and director of (very!) low budget fright flick, Midsummer Night's EVIL and the sequel webisodes series, The Hatchet Woods HORROR.
