Alex Grecian's The Black Country sees the Scotland Yard Murder Squad return in a gruesome historical thriller When members of a prominent family disappear from a coal-mining village - and a human eyeball is discovered in a bird's nest - the local constable sends for help from Scotland Yard's new Murder Squad. But Inspector Day and Sergeant Hammersmith have no idea what they're about to get into, and the more they investigate, the more they realise they may never be allowed to leave.
