Now You See Them by Griffiths, Elly

Three young women have gone missing.

A girl called Rhonda has vanished from her boarding school. Maybe she ran away, but there are disturbing similarities to the disappearance of two other young women – those too thought not to be suspicious.

But where are they?

Detective Edgar Stephens is under pressure to solve Rhonda’s disappearance, but it is his wife Emma, herself a former detective now frustrated at being just a housewife, who concludes there might be a connection between the three cases.
