Renko in Cuba, depressed and suicidal for reasons that may well enrage the reader, though initially barely engaged with the identification of what may be the body of an old frenemy, is glavanised when a murder attempt interrupts a suicide attempt to mull is way through a labyrinthine plot. Extremely well written, brilliant characterisation and descriptions of place, I particularly liked how so much of the confusion in the plot turns out to come from the fact that nobody involved actually knows what happened to the dead body at the centre of the story.
