If one tries to answer the question: `what is this book about?`, the only words that come to the mind are: `about the leadership and about the responsibility`. Not about numbers, not about procedures, not about scandals, not about success stories. About the behaviour. What should be the right behaviour of key persons that are `engines of a company`? What role should be played by top executives, non-executive directors, chief financial officiers? How should they see their responsibilities vis-a-vis shareholders, employees and all the stakeholders of the company?
