As Fran opens her mouth to scream, the ravens continue their deadly dance . . .The locals on the quiet island stubbornly focus their gaze on one man - loner and simpleton Magnus Tait. But when police insist on opening out the investigation a veil of suspicion and fear is thrown over the entire community. For the first time in years, Catherine's neighbours nervously lock their doors, whilst a killer lives on in their midst.Also available in the Shetland series are White Nights, Red Bones, Blue Lightning and Dead Water. Ann Cleeves' Vera Stanhope series (ITV television drama VERA) contains five titles, of which The Glass Room is the most recent.
