Maigret and the Old People by Georges Simenon

Inspector Maigret is called to the home of the Comte de Saint-Hilaire, a highly respected official who has been found shot dead in the study of his elegant Parisian home. The violent death of this distinguished former ambassador – an old man without political secrets or enemies – confounds the detective. Then a mysterious bundle of old letters leads him closer towards a tragic truth.
