Greeted by his enthusiastic sergeant, O’Rourke, Sam Mason finds himself plunged into a challenging investigation to discover how Harry Armstrong met his death in a vat containing BB Sauce – a scene that threatens to put him off BB Sauce on his bacon sandwiches for the rest of his life. Together with Sergeant O’Rourke, Mason follows a trail of seemingly unrelated events until something becomes very clear. The death of Harry Armstrong was certainly murder, and might well be connected to the tragedy unfolding at nearby RAF Fauld. While the uncertainty of war continues, Mason and O’Rourke find themselves seeking answers from the War Office and the Admiralty, as they track down the person who murdered their victim in such an unlikely way.
