The Timothy Files by Lawrence Sanders
Timothy Cone, ex-Vietnam vet is a very determined man, with a highly evolved sense of justice and a nose for a scam. Without exception, every one of his most routine investigations results in big time-trouble. Crooked real-estate agents, and sinister fertility clinics are some of his targets. The author has written The Anderson Tapes, The Morrow File, four Deadly Sin books and The Eighth Commandment.
