When a body is discovered beneath the ancient yew trees on the South Downs, the quiet village of Millbrook is shattered. Detective Eleanor Hayes arrives to find a community steeped in secrets—smugglers' tunnels, bitter feuds, and a vanished family heirloom. As fog rolls across the chalk hills, Eleanor uncovers cryptic clues hidden in a dead man's diary. Every villager harbors something to hide, and someone is watching her every move. Racing against time before another victim falls, Eleanor must untangle decades of deception to reveal a truth buried deeper than the ancient barrows themselves.
