The Iron Glove

Description for THE IRON GLOVE by Ronald Tierney:

THE NAKED LADY WASN'T YOUR AVERAGE FLOATER

She was, in fact, Sally Holland, wife of Indiana senator David Holland, half of Washington's Golden Couple. Within hours, a suspect is arrested, a young Latino boxer believed to be her lover. Though not at all convinced the police have the wrong suspect, private investigator Deets Shanahan nevertheless agrees to do some digging for the defense.

Another dead body later, along with some answers that just seem too easy and pat for a P.I. who has been around long enough to know the difference, Shanahan dives into the dirty side of politics and the dark side of passion--and the hideous secrets a killer is desperate to hide....

This is #3 in A Deets Shanahan Mystery.
