The pleasure of the search surpasses the glory of the find. Such is true in the Sixth Coin, which continues the saga of Jerry Cummings and his adopted son, Hassan, principal owners of Dinner Key Yacht Charters in Miami, Florida. This story begins in Barcelona, Spain, when an unremarkable man simply dressed in casual clothes is found dead on a non-residential back street. The cause of his death is not visually evident. There was no blood on the body or the surrounding pavement. It took the examination of a forensic pathologist to determine that he probably died from a head injury as a result of a fall. The Columbian driver's license and the modest amount of currency in his wallet, together with the style of his clothes, suggested that he might be a maritime worker on a vessel visiting Barcelona. Since his full wallet was not taken, only the evidence that his death did not occur at the location where he was found caused the police to believe foul play was involved. With such slim evidence and no reports of a missing person, the case did not receive much attention at Cuerpo Nacional de Policía de Barcelona (CNP). Only after a newly appointed detective in the CNP is assigned to the case does the dead man's connection to the world of treasure coin collecting become evident. When the investigation and action extended to the Caribbean Sea and the geographic area known as the Spanish Main, the Dinner Key Yacht Charter Company (DKYC) became involved. The company's CEO, Jerry, is an ex-Navy SEAL who enjoyed a reputation as a troublesome but extremely capable warrior. For Jerry, any threat to the tranquility in the DKYC cruising area and the safety of his customers always draws his interest and presents an opportunity to relive the activities he enjoyed in the Navy.
