Doctor Assassin: A Medical Science Thriller is a work of fiction in the thriller, mystery, and suspense subgenres. It is suitable for the general reading audience and was penned by author Mark R Belsky. The book follows ex-assassin Max Dent who has managed to establish himself as a well-regarded heart surgeon working in the USA. After being persuaded to take one last mission for his former employers, he quickly finds himself at the center of a plot that could claim more innocent lives than the Holocaust. Max must work with his girlfriend Lilah to stop both a deadly new disease and those who have worked to propagate it.

This was immediately a refreshing and exciting twist on the espionage thriller with the medical drama elements of the story providing an accessible ingredient that worked with the more traditional spy story elements to create an original take on the genre. Author Mark R Belsky has created a dynamic and engaging protagonist in Max Dent, one who will hopefully form the basis of a series, given his unique perspective and skillset. It was an excellent duality of his character to have him saving lives in the context of the Hippocratic Oath and also that of an international assassin, and the author wastes none of the dramatic potential that such a character innately holds. Overall, Doctor Assassin is an exciting page-turner that establishes a refreshing and engaging rhythm that builds on the already existing tropes of the spy thriller and creates something new that is unmissable.
