The Drowned Glen. The Unmapped, #2

They said the glen was empty when the water came. An old woman spent a lifetime proving they lied. Forensic cartographer Iris Calder reconstructs the truth of places for a living. So when a letter arrives from a seventy-four-year-old woman in Wick - carrying a death toll no official record will admit - Iris follows it north to Glen Sennach: a Highland valley deliberately flooded for a reservoir in 1966, with a house, and thirteen people, still forty feet beneath the surface.
They were signed off as evacuated. The paperwork is flawless. Only the loch - and one survivor who never stopped counting - say otherwise. To prove what the water has hidden for six decades, Iris and her sister must raise a drowned glen from the two things a flood can never move: a skyline and a river. The Drowned Glen is a haunting, atmospheric Scottish crime novel - Book Two of the Iris Calder series, for readers of Tana French, Ann Cleeves, and Jane Harper.
