Rebus, Ready for Retirement
By Ian Rankin
Little, Brown. 421 pp. $24.99
There's a moment in "Exit Music," Ian Rankin's 17th -- and, he says, last -- novel about Detective Inspector John Rebus, when a man with a tape recorder explains, "I'm putting together a sort of soundscape of Edinburgh. From poetry readings to pub chatter, street noise, the Water of Leith at sunrise, football crowds, traffic on Princes Street, the beach at Portobello, dogs being walked in Hermitage . . . hundreds of hours of the stuff." That could be Rankin himself speaking, because in the Rebus novels he's provided a portrait of his chosen city that's as rich, detailed and loving as any that any crime writer working today has given us of any city in the world. "Exit Music" is far from the best of the Rebus novels, but if it is truly the last of them, attention must be paid: This has been one of the best police procedural series ever written.
