Query: For the dedicated mystery buff and the ardent baseball fan

In A Difficult Trade: The Baseball Mystery, author Sam Leonard spins a complex tale of greed, arrogance, desperation, and good detective work when the owner of National League's Florida Sailfish orders drastic cuts on the ball club, including Dick Johnson, a home-run-hitting outfielder with a sixty-six million dollar contract and a no-trade clause. Johnson is shot outside a Miami strip club. Enter Miami Police Department detective Stanley Starfish whose investigation results in confronting some of the most powerful personalities in South Florida, and a plot of twists and turns leading to an ending that is as satisfying as it is surprising. A Difficult Time is a first class treat for the dedicated mystery buff and the ardent baseball fan!
