Hudson and other members of the staff are worried about Mrs. Bridges who has been acting very strange of late. The normally fastidious household cook has been sleeping in late and generally neglecting her duties. She has also taken to locking her door, something Lady Marjorie has expressly forbidden. It all begins to make sense somehow when they enter her room and find a young baby. It seems that Mrs. Hudson, in a fit of guilt and depression over Emily's suicide, simply took the child out of his pram and took him home. The Bellamys try to make it right with the parents but they insist on contacting the police with the result that Mrs. Bridges finds herself in the dock and facing a term of imprisonment should she be found guilty. Hudson appears as a witness on her behalf and saves the day. Written by garykmcd

Mrs. Bridges steals a baby!
11 July 2010 | by See all my reviews

'Upstairs, Downstairs' rarely had episodes that carried stories and plots over into the following one - but this is the first time it happened in: 'Why Is Her Door Locked?'.

Mrs. Bridges is still suffering from shock and grief at the loss of Emily who hanged herself in the previous episode six months earlier. She attempts to assuage her guilt at how harsh she was to Emily right up to just before she died by stealing a baby. When this is discovered, a huge attempt by the rest of the staff and the family is made to protect her, and to keep her out of prison. This was Angela Baddeley's favourite episode - and one can see why.

This story also carries over into the next episode too in: 'A Voice From The Past' when it is deemed possible to call Emily from the grave! We meet two new faces here, that did not stay in the series long - nevertheless; they were popular and well-remembered. New House Maid 'Alice' (Susan Porrett) and new Kitchen Maid 'Doris'. (Maggie Wells)
