An t-Eilean (The Island)

With the evidence at the sheiling matching Sir Douglas' new account of the night, DCI Halim is set on wrapping up the case. Kat can't let her theory go - Sir Douglas is convincing, but she is sure it isn't the full story and starts to suspect that the youngest son Ruaraidh's guarded behaviour at the sheiling was concealing something. In the hills above Kat finds charred remains of what appears to be Lady Mary's diary and excerpts that hint at a deep betrayal in the family. Mystery, starring Sorcha Groundsell and Iain Macrae. In Gaelic and English
