Loudwater Mystery, The by Edgar Jepson (1863 - 1938)

Lord Loudwater is found murdered in his house one evening. Unfortunately for Detective Flexen, who is to investigate the case, Lord Loudwater was not a very agreeable sort of fellow and almost every person in his vicinity had a motive for the crime. Was it his young wife or her lover, his former fiance or even one of the servants? (Summary by Carolin)
