This episode features Alan Mandel Butler and his company Apocalypse. The Den is the stuff of nightmares for most, but what reaction did they get once they asked the Dragons for a two hundred thousand pound investment in their horror-based scare attraction? The investors may be used to being the leading characters in the Den, but how will they respond to London-based Australian Katie Olver who has them starring in her personalised romance novels? Also featured in this episode are Aberdeenshire's Eddie Middleton and his eco-friendly patio heaters, a more cat-friendly collar, and a revolutionary new hat that makes your wrinkles disappear. All that and an invention that puts an end to nuisance phone calls.
