To be fair, I think the finished cover for Shirley McKay's book will be slightly different to the above. See here.
UPDATE: Mustn't forget this one, though no corridor:

To Neville Moir at Polygon, HUGH AND CRY by Shirley McKay, the first in a series of historical crime novels set in St Andrews during the reign of James VI and starring a young lawyer, Hew Cullan. The opening chapters were shortlisted for the 2002 Debut Dagger award. UK and Commonwealth rights from agent John Beaton, for publication in June 2009.
