This is a very easy read, describing the interaction between the itinerant underperforming eponymous businessman Charlie Summers, who mets two friends, Eck and Henry, whilst holidaying in the South of France, and attaches himself to them. The narrator, Eck Chetwode-Talbot, is a veteran of Afghanistan now employed by a ruthless ex-school colleague who heads a hedge fund just prior to the global financial crisis and melt-down of the global banking system. The book has veins of light humourous observations running through it, as Eck tries to sort out what is important in his life whilst the events in Afghanistan come back to haunt him, and Charlie flounders from one failed business venture to the next. The separate threads of the characters comes together at the end, although I was wondering at times where it was all going. Really just a light entertaining story. Quite good but not outstanding.
