Blame the Baron — John Creasey

It seemed like an ordinary theft by night, at first. So why then should John Mannering, aka the Baron, take an interest? The reason -- the scene of the crime, Quinns, was owned by Mannering and known across the globe for its rare, old and beautiful things. For the first time, the Baron finds himself the victim of theft, as well as a suspect in a cold-blooded murder case.
