As a bestselling author I am increasingly impressed by the standard of novels being published by Head of Zeus. I have not read one I have disliked or thought lacking in expertise or originality.

The Salt Marsh is another of this ilk . It is a ‘haunting thriller’, so says the blurb, set in the windswept marshes of Kent and Norfolk.

I can assure you that it is indeed haunting, it is also well written and evocative with a great sense tension and of place. Clare Carson has bags of empathy, and the characters live. There is pace and rhythm. So what more can I say?

The Salt Marsh tells of Sam, who can’t lay her father’s ghost to rest. Jim was an undercover agent living a double life, and Sam has left university to find out the truth about his work.

The story moves from the nightclubs of 80s Soho to the salt marshes and shingle spits of Norfolk and Kent. I remember both – the cigarette heavy gloom of the nightclubs, and the salt laden winds of the east coast. I can also remember the smugglers’ huts but never found any buried bones. It is here, in these two arenas that Jim’s secret past beckons her. So, will Sam walk away and pick up her own life? Or become an undercover operative herself and continue her father’s work in the shadows?

Read it and find out. Let me know your thoughts. frost@margaret-graham.com
