The Sixth Window: DCI Tom Douglas, Book 6 (Unabridged‪)‬

Eighteen months after Natalie Gray loses her husband, Bernie, in a horrific hit-and-run accident, she finds love with his best friend, Ed Cooper, and moves into his home with her teenage daughter, Scarlett. But she begins to suspect Ed has a dark side - and even darker intentions. Natalie must get her troubled child to a safer place, but when Scarlett starts to hear voices coming from the empty apartment next door it seems she has unwittingly moved them into the heart of danger.

DCI Tom Douglas is also chasing the truth. As his investigation into the suicide of a teenage girl draws him ever closer to Natalie and Scarlett, will he be too late to protect them from the threat they face or from the truths that will tear their lives apart?
