The couple - played by Paula Lane and Jack P. Shepherd respectively - will be left quivering in their boots when the death of the nail technician's ex-boyfriend (Sean Ward) comes back to haunt them and the nasty truth about his body being buried underneath the concrete ground in Gail McIntyre's (Helen Worth) granny annex begins to emerge.

Producer Stuart Blackburn teased: "That particular secret will come to light at the end of spring or in early summer."

However, although Kylie killed Callum when she hit him over the head following a heated row with David's sister Sarah-Louise (Tina O'Brien) last year, Stuart has hinted there will be a twist when it comes to discovering who the murderer is.

He told Insidesoap magazine: "The discovery may not directly impact the characters you think it will."

Meanwhile, this murder storyline has wreaked havoc for the scriptwriters as they've been forced to shuffle things around after Paula unexpectedly announced two weeks ago she and her husband Tom Shaw are expecting their second child.

The couple, who got married in 2014, already have 13-month-old son Arthur together.
