Readers' Favorite reviewed the first in the series: "Film Noirs and Mini Bars (A Sterling P.I. Series) by John Kemp is an entertaining murder mystery novel with the magnetism of a Philip Marlowe mystery. Altogether, this is an excellent murder mystery novel, and even though it is set in the twenty-first century, it is an amazing tribute to the sleuths of a bygone era." And now Sterling P.I. is back! The third in the Film Noir-inspired series that can be read as a stand alone novella. Sterling may be at rock bottom but the only way is up. Or so he hopes. With an ex-wife to remind him of his parental duties, he needs a fresh case and money fast. In this episode, he is hired by Charles Swift, the owner of a diamond emporium to work undercover to retrieve a precious stone. Sterling has just 24 hours to identify the guilty party of a clever heist. He cannot afford to be derailed on this luxury Pullman train to Vienna!
