E. Phillips Oppenheim wrote most famously of secret agents and duplicitous diplomats, secret treaties and international conspiracies, moonlit Riviera casinos, Swiss hotel suites, perilous yacht trips, and glamorous trans-European express trains. Known in his time as âthe Prince of Storytellers,â Oppenheim, like the brand names of todayâs best seller lists, offered readers in the first half of the 20th century a steady, predictable, and entertaining supply of pop fiction. âThe Amazing Partnershipâ is one of E. Phillips Oppenheimâs most intriguing stories. This story deals with a young man and a young woman who make an informal partnership in criminal investigation.
