CORONAVIRUS: All UK venues closed on 16th March 2020 and there is currently no planned re-opening time though it will not be before 1st June 2020 and is most likely to be September (according to some West End producers).
Some shows have been cancelled, or closed early, but many are being rescheduled and we are trying to keep up with the changes - assume that anything posted for April to August is actually postponed or cancelled. It now looks likely that little will return till 2021.
Based upon Henry James' ghost tale. A young governess is despatched to the country to take charge of two small children by their distant uncle. Her charges appear to be the very picture of "deep sweet serenity" but there are sinister forces at work and her idyll is soon to be destroyed by terror.
