In upcoming scenes, over at Number 3, Michael shows Sarah another load of designs and suggests they must broaden their horizons by bombarding fellow retailers listed by Stephen.

At the factory, the trio watch on as Beth Sutherland (betraying Carla in the process) works overtime on their new samples.

Having spent the entire night on the machine, Beth informs Michael that it's become jammed and if her boss Carla realises, she'll cotton on to her moonlighting.

Elsewhere, Sarah promises husband Adam that she's willing to consider starting a family with him when the time's right.

She later meets up with Michael and Rufus (from Donahues) to show the latter the samples, Stephen also escorts the potential investor around the factory.

Suddenly, Carla returns to the building, forcing Stephen to quickly steer Rufus in another direction.

In the Bistro, Rufus quizzes Stephen, who lies about Carla being his personal assistant. This does the trick and Rufus confirms he'd like exclusive rights to their products.

There's another twist in the story when taxi driver Peter Barlow (Carla's husband) ends up giving Rufus a lift. Peter is surprised to learn that Rufus is in town to strike a deal with the factory.

Meanwhile, Sarah, Michael and Stephen toast to their success back at the Bistro, just as Peter reveals to his wife that Rufus is involved with the factory.

Will Carla realise what's been happening?
