As prior commentators have noted, Hart has a grasp of the detail of Collins early years and London life greater than any that has appeared in print. Hart's point of view is clear; Collins was power hungry, manipulative and driven - is any successful politician not! His enormous administrative skill, particularly in a person with little forma education, Hart dams with the feint praise that Collins was perhaps better suited to be a skilled auditor and accountant than politician and statesman. In Hart's account what fails to be made clear, apart from just context, is the energy and organizational abilities of the man in running successfully the multiple interlocking organizations that he created from almost nothing in circumstances post the Easter Rising that were far from ideal and riven with factional disputatiousness; in the twentieth century revolutionary and insurrectional logistics have not been easy for even the great powers with infinite resources to manage with any degree of success. Most of all, Hart does mention en passant but fails to convey any understanding of overall context, either in the narrow sense of the various groups who required managing; the chaos created by the troubles; or the wider British domestic and imperial politics. A work that contains much factual information but fails as a biography to convey anything of Collins' achievement understood in the context of his origins or his times.
