Ian Rankin was born the same year as me, but he has been channeling a much older man since 1987. Rankin is the author of the Edinburgh-set crime novels featuring police detective John Rebus. I am reading 64-year-old Rebus’s “retirement” novel right now, ‘Exit Music.’ [Note to self: cast Alan Rickman as John Rebus in the movie playing in my head.] Kinda don’t want it to ever end.
