The Scorched Earth

2019

Who really killed Leo Fenton? Two years ago, Ben Fenton went camping with his brother Leo. It was the last time they ever saw each other. By the end of that fateful trip, Leo had disappeared, and Ben had been arrested for his murder. Ben's girlfriend Ana Seabrook has always protested his innocence. Now, on the hottest day of 2018's sweltering heat wave, she receives a phone call from the police. Leo's body has been found, in a freshly dug grave in her own local churchyard. How did it get there? Who really killed him? St Albans police, led by DCI Jansen, are soon unpicking a web of lies that shimmers beneath the surface of Ana's well-kept village. But as tensions mount, and the tight-knit community begins to unravel, Ana realises that if she wants to absolve her husband, she must unearth the truth alone.

The Fall

2022

The sins of the past echo in the present in the new literary thriller from Rachael Blok. The wind is cold this high up. The man shouts out, but nobody hears. The cathedral roof has caught his fall, but it will not hold him for long. The night is dark. And it is such a long way down... On Good Friday, the verger of St Albans cathedral was supposed to be preparing the Easter service. Instead he discovers a man lying dead, fallen from the famous fifty-foot-high spire. Did he jump, or was he pushed? For DCI Maarten Jansen, it's a simple case of suspected suicide. Until a stranger, Willow, who witnessed the jump, prompts a deeper investigation into a long-buried past, involving a mental hospital, a pregnant woman, and fifty years of silence. As Willow's own family history entwines with the case, Jaansen starts to wonder how everything is connected. The Fall is a haunting literary thriller about loss, trauma, silence, and how our past shapes who we are.
