Who Played Mrs Alexander in The Curious Incident of the Dog in the Night-Time

Mrs Alexander is a role in The Curious Incident of the Dog in the Night-Time, a play that opened West End in 2013.

Christopher, fifteen years old, stands beside Mrs Shears' dead dog. It has been speared with a garden fork, it is seven minutes after midnight and Christopher is under suspicion. He records each fact in the book he is writing to solve the mystery of who murdered Wellington. He has an extraordinary brain, exceptional at maths while ill-equipped to interpret everyday life. He has never ventured alone beyond the end of his road, he detests being touched and he distrusts strangers. But his detective work, forbidden by his father, takes him on a frightening journey that upturns his world.
