The Beasts of the Black Loch

Dr Ava Dickens visits remote Dorcha Hall, where her godson Alastair hopes to save his crumbling Scottish estate by turning it into a hotel. But when a guest dies after drinking poisonous insect repellent instead of whisky, Ava's scientific instincts tell her it was no accident. Drawing on her expertise in animal behaviour, she sets out to uncover the truth before more lives are lost.
