`Vacant Possession' is the sequel to `Every Day is Mother's Day' by Hilary Mantel.
`Vacant Possession' begins 10 years after the events at the Axon's house which ultimately led to Muriel being placed in Fulmers Moor in the Greyshott Ward as part of her rehabilitation to eventually return to society, which she does, but Muriel has changed, she can now mimicry (mimic) and is a mistress of disguise, one of Muriel's hidden traits is that she watches people and for ten years she has been watching everyone in Greyshott Ward.
Colin Sidney is now living in the Axon's old house, his sister Florence still lives next door, his wife, Sylvia has reinvented herself, she has become more confidence, more sociable. Isobel Field is now married and no longer a social worker, everyone is living their lives but unknown to them, Muriel is amongst them.
`Vacant Possession', I felt was the stronger of the two books, you find out more about Muriel and also how devious (and scary) she is, with `Vacant Possession', you find out the lengths which Muriel will go to, to get her revenge.
An interesting read.
