Rebus book 20, I can't believe i have been reading about this wonderful creation since the late 1990's and he never disappoints. I used to worry abt how a hero ages over a series but have now decided I don't care just keep going, if rebus is 100 and still locking horns with big gear cafferty as he does here I won't care. In this bk he is retired but back to stick his oar in a Glasgow Edinburgh crime lord face off.
