Sleep TIght by Rachel Abbott

Sleep Tight is the 3rd in the DCI Tom Douglas series, however Tom's life plays a secondary part in this and it's not important that you need to have read the others.

Olivia's gone missing, but does her husband know more than he's telling?

This story weaves from suggesting one thing to another and makes you believe one thing, then twists it to the opposite.  I was totally gripped.
