Harry Potter actress Katie Leung (Cho Chang) is set to be in Cat Amongst The Pigeons, an episode of the show Poirot, which is an adaption of Agatha Christie’s novel. She plays Hsui Tai, a pupil at a private all-girls school who helps the legendary sleuth solve a murder at the school and the mystery of a kidnapped Middle Eastern princess.

A spokesman for the show said: “We’re absolutely delighted to have Katie on board. She’s a very talented actress and a great addition to the cast.  She helps Poirot spot a couple of clues which let him piece it all together.”
