The actor played haunted homeowner Alison in the series, who suffered a near-death experience shortly after inheriting the historic Button House, which allowed her to perceive its apparitional inhabitants.
There's certainly no shortage of classic Ghosts episodes across the run, but Ritchie told RadioTimes.com in an exclusive interview that her favourite remains one of the earliest chapters – and the first that the cast and crew ever shot.
"We had fake First ADs [assistant directors] and real First ADs and fake cameras and real cameras," continued Ritchie, on the challenge of filming a show-within-a-show.
Ritchie also fondly remembers early hints about The Captain's sexuality – a running plot thread finally paid off in season 5 – which began to be sewed in Free Pass as Ben Willbond's character developed a fascination with a male member of the crew.
After five years on Ghosts, Ritchie has moved into more dramatic roles as of late, including the icy Kate Galvin on Netflix thriller You and DS Ashleigh Francis in ITV's brand new Code of Silence, starring Rose Ayling-Ellis.
