I saw it advertise in Closer mag a few months back!
it is a beige ish colour cover with the oicture is off as though your standing at the front door looking in ( i think there is a rocking horse in another doorway!!)
Its about a woman who returns home to find her front door open and her child missing, the dad is asleep ( i think) either the woman or the baby is called Sophie!!!
Sorry i know it seems hard but thats all i ave to go on
Thought you guys might be able to help
Thanks
