At first, skip tracer Johnny Midas' mission to Mockridge was as familiar as an old tune—to find a missing bank clerk. But swiftly this changed—the search had a jazz beat to it now. The only friend the bank teller had claimed in town was a has-been jazz trumpeter named Buck Legrande, a man desperately trying for a comeback. Though Buck himself swore he didn't know the missing man, he must have known a lot about some other shady people. Buck's comeback soon ended in his murder. Johnny knew he would have to use everything he had to solve this one...but he didn't count on being as sharp with his ear as he would have to be with his gun!
