Burning Ledgers

They tried to bury the past. Now the past is burying them.

Tom Marlowe's partner Trix Preston hasn't mentioned Operation CASTLE ROCK in five years. She doesn't need to – it was pre-MI5 hacking work, corporate espionage to pay off a debt, nothing worth remembering.

Until three GCHQ analysts connected to CASTLE ROCK turn up dead across Europe, one every seventy-two hours.

Someone is eliminating everyone who knew about the operation – a five-year-old MI5 project buried in Edinburgh's financial district where British Intelligence's black budget meets corporate fraud.

Trix's name is on the list.

The assassin is already in Scotland.

And with the pattern holding, she has three days before the killer comes for her, and the only person who knows why someone inside MI5 would want CASTLE ROCK erased is a ghost from Trix's past who shouldn't still be breathing.

Now Marlowe must protect his partner while hunting for files that prove who sold out CASTLE ROCK five years ago. But in Edinburgh's shadows, the deeper he digs, the more he realizes the woman who taught Trix to survive might be the same one trying to get her killed.

Some secrets stay buried in ledgers. Others stay buried in bodies.

And in Edinburgh, they're burning both.
