The mysterious drowning of Ranald Buchanan, an acclaimed Gaelic fisherman-poet, on the first night of the literary festival hardly sets the right tone for the celebrations. For one thing,
it rekindles age-old fears about the Selkie, the seal-man who claims his victims and drags them beneath the waves. Torquil McKinnon, recently promoted to the rank of inspector in the
Hebridean constabulary, soon has his hands full. Not only has his old flame, crime writer Fiona Cullen, returned to the island for the festival, but also it appears there is a serial killer
on the loose.
