Eric in Downtown Abbey

Eric’s lost his job and can’t get any work. Bev comes to the rescue by finding them work at Downtown Abbey. The place is run by Lord Trentham as if it’s still 1910 and the below-stairs staff are a motley crew led by Sarson, the Butler, two footmen, a couple of ladies’ maids and the Chaffeur.
However, when things start to go missing Eric and Bev find themselves in trouble. Is Eric guilty? Has Bev been able to persuade them she's a good cook? Will there be a load of 60s hits played through the evening?
