Ghost in the Machine (Police Scotland 2, Paperback)

Revised 2025 edition...

Think you're safe online? Think again.

DC Scott Cullen is still green – just three months with Lothian and Borders CID.

But when a woman vanishes after meeting a date on Schoolbook, Edinburgh’s trendiest new social network, Cullen thinks it’s a routine missing person.

Then her body is found.

As a second woman is found dead, the hunt for a serial killer begins. DI Brian Bain is convinced it’s the first victim's ex-husband. Cullen isn’t so sure — and he’ll risk everything to make sure the right person is brought to justice.

With the killer still out there, Cullen’s about to find out just how personal murder can get.
