In similarity with other Kevin Johnson books, this crime thriller is best enjoyed by reading a chapter or two at a time, then to ponder the plot to the readers preference, then returning to do the same again. This can provide added reading enjoyment and mental stimulation. Our hero, Dr. Dan Thompson, ex RAAF pilot, having recently lost his wife of 20 years to bowel cancer, takes a break from his Sydney medical practice and tours Europe and England only to be caught up with the Covid 19 virus epidemic and the resultant travel restrictions inter country. To return home, he is lucky to be offered a passage on a cargo vessel En-route to Fremantle/Perth Western Australia. The ship is hijacked by Indonesian pirates, cargo stolen, and the ship released, sailing onto its destination Fremantle. Enforced into a 14-day hibernation period, he endures the confinement, then meets his daughter and together they plan a driving trip to Darwin that should if correctly timed, allow him to eventually cross borders to return to his Sydney home. After encountering a nasty road accident, Dan meets the crew of a Royal Flying Doctor aircraft who as an urgent fill-in, seek his expertise at least over the next few weeks. He meets the Senior Sister Jenny Cousins, and together they save lives and begin to enjoy each other's company. It is then Dans old enemy finds him and attempts to complete his life's desire; to injure Dan in the same way Dan did to him. Shot him in the knee, all those years ago. This is Liu Wei Cong, ex Indonesian Army now drug distributer and money launderer. He has amongst his clients list, General Peng Fu of the Chinese Republican Army, Councillor and one of ten, sitting on China's highest court. The business these two do is in big numbers, with the General believed to be responsible for the original spreading of Covirus 19, via international travellers, and various airport terminals. The plot is fast moving, but believable, and if not rushed by skim reading, an enjoyable read should be experienced.
