Showing Mourn Not Your Dead by Deborah Crombie

The murder at Holmbury St Mary was not one that Superintendent Duncan Kincaid of Scotland Yard would relish investigating. A man has been beaten to death in his own home. A man who just happened to be Commander Alastair Gilbert of the Metropolitan Police... Only adding to Kincaid's problems are his tangled personal feelings for Sergeant Gemma James. And in an investigation of this importance neither can afford a breakdown in their relationship. Combining subtle emotional nuances and psychological insights with the intricacies of police procedure, Deborah Crombie produces a powerful contemporary mystery in the classic tradition.
