Oliver Barnett is found murdered in his office. The investigation into his death reveals a man that his younger brother, Simon, does not recognize-a callous blackmailer. But was this the reason for his brutal demise? Simon sets out to clear his brother's name, and to demonstrate the innocence of the woman he once loved. Agatha Christie chose His Brother's Killer as winner of the Collins' Crime Club Detective Novel Competition in 1961. A hugely underrated and unjustly neglected writer, D.M. Devine (1920-80) wrote 13 crime fiction novels in all. All of his books are well written and plotted, qualities prized by the Queen of Crime herself, who remained a fan of Devine's throughout his writing career.
