In Her Shadow by Emma Christie

Dave Kellock is a pillar of the community in Portobello, Edinburgh – a tireless volunteer who never misses a chance to help others.

Dave Kellock is also a fraud. Now that he’s made the King's Honours List and his photo has been in the paper, the truth won't stay buried for long.

When a local teenage girl goes missing, Dave is suddenly a suspect. Will he find this girl? And just how is she linked to the secret he's been keeping all these years?
