The Castleton Affair A Gripping 1920s Historical Mystery

A government aide kidnapped, a French diplomat murdered, a killer to uncover... When mystery writer Marius Quin and his sleuthing partner, Lady Bella Montague, are hired by a secretive stranger to find a missing civil servant, they immediately set to work. Ernest Castleton was taken at gunpoint days earlier, but with the help of his distraught fiancée, Marius and Bella uncover a vital clue. Ernest hid a cryptic letter in the British Museum, and it sends the intrepid duo on a trail that stretches from the centre of London all the way to the English coast. The investigation takes on a new twist when they arrive at the home of the British Foreign Secretary only to find a French diplomat murdered in the Grand Hall of the palatial property... But who pushed Monsieur Rochefort to his death, and what does it have to do with Ernest Castleton's disappearance? Marius and Bella must choose from a nefarious spy, a double-dealing diplomat and any number of spoilt aristocrats if they wish to catch the killer.
