Walker Jameson has escaped from prison using a strange method leaving the authorities a real puzzle as to how he did it. Jameson had only a short time left on his prison time that made this escape even more questionable.
Deputy U. S. Marshall Tim Rackley is called into the investigation. Tim and Bear, who is a close friend to Tim and his family and also in law enforcement, start their search for this cunning man. Jameson was a former military ranger and knew all the tricks to avoid finding him, much less capturing. He also knew how to kill and torture while obtaining information. Tim is married to Dray, also a cop, now on maternity leave. The life that Tim leads does not allow much time with his family but what time is possible is so important to the entire family.
Jameson has a nephew, Sam, who was seven-years old. Walker's ex-wife, Kaitlin, was raising Sam as Walker's sister, Tess, Sam's mother, had been killed. Sam has a disease that is shutting down his liver. Walker learns that Tess had gotten Sam on a list for a new trial drug treatment for the liver disease he had. At the start the program was free, which was all that could be afforded since Sam's medical coverage had lapsed.
This book opens up the reader's eyes as to what some of the large pharmaceutical companies do to get their products to market and keep them there. It also provides a very plausible scenario that many drugs are kept off the market because the profit might be lower than another researched drug they know will work better.
Walker continues on a long spree to find Tess's killer during which he murders several that he felt were responsible in her demise. He also learns that the pharmaceutical company was playing games with Tess and Sam's life. When this company told Tess that Sam would go off the program if Tess would agree to a liver transplant for Sam instead of the drug program. They fed Tess a line of bull that a new liver would be much better for Sam than an experimental program.
Walker's search for the truth causes him to cross paths many times with Tim and Bear, as well as other law enforcement officers. As Tim and Bear finish their investigation of the prison break, their search for Walker and the truth of what is occurring at the pharmaceutical company intertwine and make for a very interesting mystery and intriguing activity for all involved.
A very enjoyable read that occasionally gets bogged down but not for long. It gets active quite fast with Tim and Bear, their families, and all the research they are compelled to do to get to the truth and the real victims in "Last Shot!"
