Framed in Blood — Brett Halliday

When a blackmail scheme goes wrong, Mike Shayne is left to pick up the pieces
 
Bert Jackson could have been a great reporter, if he had the patience for it. Married to a woman with expensive taste, Jackson has spent himself into the kind of debt that he'll never pay off at $62.50 a week. He needs a big score, and he needs it tonight. Working the city hall beat, Jackson has stumbled upon the greatest corruption scandal in Miami history. If he publishes it, he could win a Pulitzer. But it's money that he wants, and he'll risk death to get it.
 
Using the information in his story, Jackson plans to blackmail a powerful local official for $10,000, and he asks Mike Shayne for help. Shayne has seen too many blackmail artists wind up dead to get involved with something like this, and he warns Jackson to stay away. When the reporter turns up dead, it's up to Shayne to uncover his final scoop.

Framed in Blood is the 19th book in the Mike Shayne Mysteries, but you may enjoy reading the series in any order.
