Silent Companions by Laura Purcell

Its hard to get the right vibe for gothic fiction in our modern times. Purcell wisely decides to set her story in the Victorian period and adds a healthy dose of 'Yellow Wall-Paper' paranoia.
Soon after her marriage Elsie Banbridge is made a widow and sent to wait out her pregnancy at her husband's remote family estate, The Bridge. Her only companion is a cousin, her deceased husband's only living family, and a few servants. The estate has something of a dark reputation in the village and Elsie feels isolated. The discovery of a 'silent companion', a trompe l'oeil figure painted on a board, in a locked attic room awakens old rumors and fears. The figure, painted in the late 17th century, looks like Elsie, and soon she discovers it is not alone.
A quick read, and quite chilling. The use of the Companions, or dummy boards, was genius. Good period detail and flawless setting.
