The scorched earth / Rachael Blok.

"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."--Publisher description.
