Meet the cast of The Au Pair on Channel 5

Although Zoe doesn't initially feel the need for an au pair, Sandrine seems like a much-needed breath of fresh air. That is, until things start to take more of a sinister turn after she gets closer to the family.

However, things start to unravel for Zoe as she deals with mounting pressure, work mishaps and personal problems. As well as Bretton leading the cast as Zoe and Lupin star Ludmilla Makowski starring as Sandrine, Poirot legend David Suchet stars as Zoe's father, George.

Speaking about his role in The Au Pair, Suchet told Radio Times magazine: "The Au Pair was the first thing I had to do, it was a real page-turner. Other roles I was offered were nice, but repetitious and not quite challenging enough."
