Is this the finale for Rebus? Nobody knows. Not even Rankin himself. But one thing is for sure: this book certainly does not disappoint. With Rebus trying to follow up loose ends before his retirement, law of nature would guarantee that something will occur to ensure his walk into the sunset isn’t smooth; that’s if he makes it into the sunset at all. Cue the brutal murder of a dissident Russian poet, an enthralling plot linking a group of Russian businessmen, politicians and bankers trying to close the case, Rebus himself in the dock and the result is Rankin at his very very best.
